Yeah, unless you have a mass following at DA, I wouldn't recommend it. I paid for the print account only to discover after the fact that it's rare for people who aren't particularly popular to ever sell prints. Very disappointing... I can vouch that their quality is fantastic at least, as I've bought a couple of my own prints. I may just buy a bunch and try to sell them myself sometime. (Artist discount, gogo)
Usually what I hear is that it's best to print it out yourself, even if it is a hassle. You can try a place like Kinkos, and if you know your prints will well, then you can maybe invest in a nice printer and the ink and all that and start doing it yourself. You have more control of what's printed that way, since some places require X amount of prints to be printed at a time, or just charge bad prices *unless* you do bulk.
