Epson is ultimately the best where printers are concerned.
I use an R300 and never have, and probably bever will, use the extra facilities, so I'd be just as well served by the R200. I've never had the jets clog at all on this printer and it does do borderless prints.
The only think I'd say with you going unashamedly commercial, is think about whether you might need an A3 printer, but printers at that size have expensive appetites in paper and ink.
