IMO, it depends mostly on how much you are going to use it.
If you're talking about 100ft of crown molding and that's it, then
I would say no. If you are going to have a regular stream of
projects, then yes.

5 years ago, I was in your situation. I had never used anything
but a brush and a roller. I had a contractor replace 8 interior
doors in my house, and he wanted $1100 to paint them (doors
and jambs). I took the plunge and bought an HVLP. It was a great
move. On newly installed trim etc., you will get a professional look.

A few things to consider, however. You are probably talking about
latex "enamel" (rather than tinted lacquer) I presume. To spray
latex, you need a 4-stage turbine. That plus a good gun will run
you around $1000. Stay away from anything less. A lower
powered unit might be fine for lacquer or shellac, but you'll never
get a decent result with latex without a 4-stage turbine.

Don't expect to save much time. It is just that the nature of the
job changes from "painting" to "prep and cleanup". You will have
to mask off *everything*, because there is a lot of overspray.

Don't expect to paint walls or ceilings with HVLP. HVLP moves
1 quart of paint in maybe 10 minutes, and large area surfaces
are impossible to spray and still keep a "wet edge". If you want
to paint walls, rent an airless sprayer.

I am very glad I got my HVLP. I have slowly been renovating my house,
one room at a time. I've done crown, window molding, door molding,
and plenty of cabinet finishing. I've sprayed latex, lacquer,
shellac,
and catalyzed conversion varnish. When I compare my actual total
time to hiring a pro, I end up paying myself $50-100 per hour.

So, if you want to approach this as an ongoing hobby, then go for it.
If you'd rather be playing golf, then hire somebody.

If you do go the HVLP route, I am very satisfied with my Fuji Q4.
It does a beautiful job, I have never had a problem, and when I
have bought supplies and accessories I have dealt direct with the
factory. The owner answers the phone, he is a nice guy, and is
very responsive.

I may have been unclear in my original post. I am looking at an
airless sprayer (Graco
Magnum DX ($300)) , not a gravity feed/hvlp system. From what I have
read, the airless is the way to go for painting interior walls,
cielings, etc. Very little overspray and the ability to put product on
the walls without schlepping a roller and bucket. My foyer has an 18ft
cieling, so I will be on a scaffold about 10-12 feet off the ground. I
thought manipulating a hose and gun would be much safer and simpler
than a roller and bucket. I agree that an HVLP isnt the way to go.
What about feedback on an airless?

I've been a painting contractor for 20 years, on my 3rd sprayer, you will
not get a good job on walls without backrolling after spraying, so the
roller still goes with the sprayer, and not a one man job to spray and back
roll, dries too fast, you wont get away from that, if it were me, I'd be
cutting it in off an extention ladder, then rolling with my 14' extention
pole from the ground, pain in the ass, but I'd have it painted in the time
you took to get the scaffold up. Spraying or rolling off the scaffolding
will give you a choppy result, it will be in the way for the bottom part of
wall, even if you had an expansion joint in the middle I would still do it
off a ladder. Cut it all in with ext. ladder, then roll top 8' or so of one
wall with 14-15' ext. pole, then change to 5' and finish that wall, then
start next wall.

Greg, thanks for the input. In my continued reading I did come across
the backrolling and having a 2nd person follow as the wall is sprayed.
Probably best to stick with the roller. How would you suggest I paint
the ceiling (its 18ft). I am thinking there is no way around the
scaffold for this.

How big an entry are we talking about, if only say, 12' x 12', I'd still
do it off the ground, 18' is about maxed out for my 14' ext. pole, so I may
need to stand on the first step of my step ladder, that's why I ask how big,
don't think I'd want to much bigger then that, moving ladder and pole
around. Can some or all maybe be rolled of the stairs/landing?
