Jon - My first AB back into this was the same one you referred to. It does an "adequate" job, but for only about $75 more, you can get a good airbrush like the Omni 4000 or Iwata HP-CR (I own the HP-CR and love it) ***AND*** a compressor from Lowes and be doing circles around that Testors brush... As long as no one in the house minds a bit of noise from the compressor now and then (my wife swears she doesn't notice it much as it is in a back bedroom) or you can get a 50 foot air hose or somewhat, you will be set!!!
the biggest problem I had with the Testors AB was paint clogging... and from repeated disassembly of the nozzles to clear said clogs, having to buy new nozzles at H/L... at $8 or so apiece, it got to the point after a year; buying an all metal AB made sense...
Take that 40% off coupon to H/L this weekend and get the HP-CR for $60 and be happy! even if you have to wait a bit to get a compressor you'll have a good brush. Or you can wait and get either it, or the Omni 4000 online at www.dixieart.com for about $69.00 with free shipping...
