We like Epson...very cost effective.
If you dont know much about design, and color profiles, etc. i would then recommend a Ricoh.
We have used both and get better colors and higher quality images off epsons.
You will get people who are going to say they clog...well that is if you dont use it often. So sell sell sell and you will keep the ink flowing.
You can also do a test print every few days to keep the ink moving...it cost less then $0.01 each time we do a test print. So that is less then $1 per year.
