Pretty job, Pat!
Steve, if you notice the pics of Pat's guns...the first Debilviss shows a disposable cup system. This costs a bit for the cups, but is SOOO worth it! It saves a good 15 minutes in cleaning, not to mention the thinner it takes for the cleaning. The second pic is the standard reusable cup, and it has to be cleaned every time you use it. The disposable cups last forever between jobs, and it makes it so easy you can paint with the sprayer almost as easily as a rattle can. You can get a set in pint size for small jobs like a fender, and the quart size when painting the tub...all for the same gun.
The features I think have made the most improvement in spray guns, in the order of improvement are:
1) top loading guns...no more delay in spraying and better patterns as a result.
2) disposable cup liners...eliminates ANY chance of a vent hole dripping paint on your freshly sprayed work, and cuts cleanup to 1/3.
3) Replaceable tips...Saves having to buy 3 guns for various jobs. The finish line 3 comes with 4 tips that cover clear coat on the thin side...to fiberglass gel-coat on the thick side.
4) HPLV...a bit less overspray so paint covers more.
So...as your budget allows, make sure you get #1, and then work your way up. If you get all 4, then I guarantee you will be happy with your set-up.
Oh, and once you have your gun...let us know and we can discuss water separation, which is probably more important than spray gun quality!
