I did a lot of research on this before buying my first laser printer (with digi-stamps in mind)... and got pretty frustrated, LOL. I found a really good price on a Brother HL-2207W, and took the plunge.
I'll try to give an honest review: I had some issues when I first got it (mostly with setting up the WiFi), but I'm really happy with it now. It will take 110lb paper, if you set it for "bond paper", and use the special paper feeder and open the back, so it goes straight through. I wouldn't try anything thicker, though. (I'm trying to do most of my digis now on 65 or 80lb.) I've had a tad bit of trouble with it not being 100% straight, but that only bothers me if I'm printing text (sometimes I use the same cardstock to print a sentiment for the inside of the card). When I print digi-stamps, I don't care if they're straight because I'm just going to cut them out, anyway.
Other than that, I'm very happy. It prints super quick, and the ink doesn't smear at all. (I use pencils and OMS to color.) But as this is the first laser printer I've personally owned, I don't have anything to compare it to.
