I don't use digis much, but I do print sentiments on cardstock quite a bit using my printer. I like it a lot and it was inexpensive. I got my printer at Walmart. Here is a link:
Canon Office MX360 All-In-One Multifunction Printer ? Walmart.com
I would advise that you try to find a printer that has the paper rack outside, not a drawer inside. When the cardstock has to go through the printer and roll around a roller, it sometimes/frequently gets jammed.
If you have a printer with an outside/top-loading rack, it goes through the printer almost flat, or at a slight angle and out the front without having to curl around anything and doesn't jam.
You can't see the outside rack in the Walmart picture, but you load the paper in the back of the printer.
