Careful what you are buying. I have the TC20T compressor Viscious posted above. You are right-- it's inexpensive, and quiet, but you get what you pay for too. It's a Chinese made compressor (not that that's bad) but it's not the best quality either. Fittings are poor quality, the tank is prone to rusting, and the regulator/ moisture trap is so-so. This is a tank compressor designed and sold on the cheap. It does the job just fine though, but I have to keep mine in semi-constant repair-- I'm handy, and have a complete workshop, so it's not a problem for me, if you're not a handy person with full size tools-- you may have problems later. Here's my list of fixes for my compressor:
1) split/cracked air outlet elbow to the regulator-- fixed with a "c" clamp, plumbers putty and JB weld epoxy. Works fine now-- I had to do it that way because replacement parts for these things are almost impossible to find, and when you do find them, usually the threads don't match up to the cheap machining. By the way, we used to sell these in the LHS where I worked for a while, and this is not an isolated problem-- I've fixed others too.
2) regulator failed, bought new regulator.
3) Moisture trap works fine, but it's difficult to drain completely, causing rust build up--- but that's really a regulator design issue. It doesn't affect operation.
4) tank fills with water (my own fault living in a humid environment and not draining it often enough) which rusts the bottom of the tank, causing a pinhole leak (fixed with JB weld epoxy). The drain is a large nut that is difficult to remove unless you have full sized wrenches. The upshot of this is I still have a very minor leak around the putty patch-- so minor I can still keep constant pressure in the tank, with the compressor running about every 20 minutes-- enough to cool down-- but now my tank is "self draining"-- the minor leak pressures all the water out as I'm using it. I just have to keep a paper towel under the compressor to absorb it-- maybe that's a benefit because now I don't have to drain the tank!
So, you get what you pay for. I've had mine about eleven years now (the names change, but it's the same compressor-- mine was just labeled "TC20T" without the "Master Air" logo). Don't get me wrong-- I actually love my compressor, it has character, but I can fix or repair most anything. If you can't do that, start with a high quality/low maintenance compressor, which will cost more. I also have two other tankless compressors to fall back on if this one dies completely. In contrast, my tankless Binks compressor is 50 years old, and except for some paint spots and dust, it still runs like new when it was purchased in 1968 when I was 15 (for an exorbitant cost of about $30, which is equivalent today to about $200 given inflation). My dad bought it and I used it for everything until I purchased the TC20T.
