   I would suggest looking for a Sata jet 90-2rp gravity gun. I picked a new one up at a discount for $230 USD. I believe they normally retail for somewhere around $300 USD. There are certainly more expensive guns out there. But, my other main gravity gun (DeVilbiss GTI) retails for over $400 USD and this Sata sprays every bit as well as the DeVilbiss.

   This Sata is not technically an HVLP. But, it is a low pressure gun and does comply with all of the EPA regulations which lead to the creation of HVLP technology. It's basically the next generation technology after HVLP.

   Homestead Finishing has an Asturo (Italian-made) HVLP conversion gravity gun on sale now for $189.00.  That is the best deal for a quality gun I have found.  The best part is that you get free consultation from Jeff Jewitt, the owner, on your needs.  Jeff is an acknowledged finishing expert, and author.  He was a huge help to me recently, and this is a topic where advice is very hard to come by.  Even this forum can be a little stingy with spraying advice.  I haven't used my new gun yet, but I confident I can get answers to my questions from Jeff.

   Are there limitations on what you can spray with HVLP?  Stains, oil based, water based top coats?  Would you use such a system to spray interior house paint as well?

   I haven't had any problems with conventional and Accuspray HVLP for the relatively thin finishes, sealers, stains and dyes used in woodworking or automotive work.  Latex house paint can be sprayed conventionally with a huge fluid nozzle and a pressure pot.  If you thin it more than 2% latex is pretty much ruined.  I use a roller unless it's several rooms in which case I rent an airless.John O'Connell - JKO Handcrafted Woodworking

   We trained hard, but it seemed that every time we were beginning to form up into teams, we would be reorganized.  I was to learn later in life that we tend to meet any new situation by reorganizing; and a wonderful method it can be for creating the illusion of progress while producing confusion, inefficiency, and demoralization.

   I recently bought a Porter Cable HVLP gun. I have sprayed about 3 gallons of shellac based white primer and almost 2 gallons of Urethane white enamel. Does an excellent job with these finishes. This is the first hvlp conversion gun I have used, most of my spraying in the past was with conventional siphon and pressure feed guns.I save them for emergency use only ,now that I have hvlp.

   I bought mine from Tyler Tools, there online, excellent service and prices.

   I've got the Porter-Cable gun, like-new for sale, if you are interested.   My compressor is too small to run it.

   Thanks for the offer but I do not do enough spraying to warrant a second gun. The PC is for relatively small compressors. Why don't you hold onto the gun, you may eventually get a larger capacity compressor. I use a 3 hp Quincy compressor with a 20 gallon tank. I believe it's rated for 9.2 @ 40 and 7.8 @90. This easily runs the PC spray gun.You could also use an auxillary air tank to hold more air. I kept a 30 gallon air tank from a compressor that was shot. I use the air tank when I really need a lot of volume,such as air sanding etc.I just connected the compressor to the air tank,with a short hose and plumbed the tank with a gauge and regulator.

   Mike,

    

     What is the CFM rating on your compressor?  Have you tried spraying water-based finishes yet?

   I have only sprayed oil based enamels and shellac based primers so far. I haven't tried water based finishes as yet. The shellac based primer was thinned with one ounce of alcohol per quart of primer. The enamel was thinned with paint thinner at two ounces per quart. The compressor puts out 9.8 cfms at 40. I leave the compressor set at 90 lbs and set the regulator at the gun at 55 lbs for both finishes.

   You may have to change the needle or use flow control to thin water based. Check on a finishing website for better info. I have done a good bit if spraying, but I am not as well versed as the experts.There are several websites,do a google swearch for them.
