craftgrrl | Advice for Making Professional-Looking Buttons

Hi. I'm going to be buying a Dr. Don 1" button maker soon to start making buttons but I'm really at a loss for what to do regarding a printer and printer paper. Do any of you do button-making professionally? I want them to be really high-quality because I plan to have them in an online shop. Any thoughts? My printer budget is about $200-300. I'm also hoping to use this printer to print stationery so any thoughts on that would be helpful as well. From what I've read, it doesn't seem like a good idea to try to do your own prints from home, but I was thinking maybe stationery would be do-able on a good printer.

Any thoughts/suggestions would be greatly appreciated.
Thanks.
