Better late than never... I hope...
I've recently been comparative shopping for an airbrush & compressor setup.
Yes, Dixie Art has the lowest prices that I could find for airbrushes... But...
AirBrush-Depot seems to have the best prices for airbrush & compressor sets if you want or need a super quite compressor.
Their ABD TC-20T compressor is quieter than a sewing machine, but a bit noiser than a refrigerator and pumps out 60 psi.
I don't have a Lowe's near me, but I checked out compressors at Home Depot and Wal Mart.
The quietest one I found was at Wal Mart, a CP going for $70.00. It's
"slightly" quieter than one of those air pumps around town for filling
up your car tires (like you find at gas stations or convience stores).
Not something for in the family room or while listening to the stereo,
and will definitely keep everyone awake.
Hope that helps a little and I'm not too late.
