More infomercial fare, but inneresting in that this appears to be a *true* HVLP sprayer.... well, mebbe "true" hvlp sprayer.... lol
Inyway, all told, about $100. You carry the compressor on a shoulder strap. Looks like very little blowback. The infomercial was mildly inneresting, and altho the demo's were of course pre-biased, the seamless painting of rough surfaces is proly truer than they portray, as they are so determined to muck up *everything* in their favor.
To wit, they virtually dismessed -- or rather, totally disguised -- the need for masking, giving the impression you need not mask any more than you would for brushes/rollers. Not having used hvlp, I'm assuming this is really a stretch....
Compare with HF's ditty: http://www.harborfreight.com/high-volume-low-pressure-spray-gun-kit-44677.html
Also, I believe you can use a paint pot (like http://www.harborfreight.com/catalogsearch/result?q=paint+pot) for more capacity, with hvlp. You would need a sep. supply of compressed air, which sort of complicates things, but in a sense, should give the best of both worlds -- more capacity, lighter spray gun, more thickness control. But christ, the g-d paint pot is as much as the hvlp unit!! wtf???
I imagine the paint pot pressure would have to be pretty low, *and* stable. The regulator on the HF paint pot does neither particularly well, so be prepared to substitute it.
The real Q is: is Paintzoom a toy? Proly is. Might work well for a while. I myself would (and will sooner or later -- too much blow back with my hplv sprayer, messy) go with the HF unit, esp. since some here posted some time ago that it does a reasonable job.
Inyway, thought this was inneresting, and additionally inneresting was, in the 10 min or so I watched, they never described the system as "hvlp"..... heh, mebbe it isn't???? LOL
