I bought all three of my heat presses "used" on Craigslist. I have been pleased with all of them!
JP12
DK20
Chinese hat press
I also bought 3 refurbished printers:
Okidata 5800cdn
Epson 88+
Epson 120
In Feb I invested in a New Dell Inspiron XPS 1530 laptop (I already have my graphics software, I use an old version of Photoshop)
Then very recently I bought a new USCutter Laserpoint 24 cutter.
I think my equipment purchases are now done for awhile, I have everything I put on my wish list last fall.
I have earned many times more than I paid for them in just 8 months. I mostly sell my shirts at horse shows where I show and vend. I work full time and moonlight running a series of niche websites selling all sorts of things including of course apparel and hats. The apparel and hats part of my moonlighting satisfy my need to be creative, I love it!. I also like to make jewelry and websites.
My day job is working for a large company in the IT department as a Web Release Manager (over 130 domains).
If you do your research, plan and buy your equipment carefully you can make a very prosperous side business! Good luck
