Gocc-what?

I am thinking about investing in a print gocco kit. I want to do small runs of prints and am tired of spending crazy amounts every time I want something printed. I love the idea of doing it all from home and getting less than perfect yet hand-done results. Of course, the big hunka-chunka Arts for Paper looks pretty tempting, as it does bigger than post-card sized prints but will set my little business back a cool 1k — so perhaps the PG5 is a better option as it’s the model for the “unsure” which I guess is me. Any purchasing tips from you seasoned Print Gocco-ers out there?
