I've owned the Cuttlebug for years and like it for embossing. I don't own any other tools like the Wishblade or Cricut. I don't know what else is out there that embosses. I'd be interested in reading the feedback on this myself. One thing to keep in mind is the embossing folders for almost every machine are about 4 x 5.25", so you can't make full-sized borders for a 12x12 page unless you emboss more than one piece and place something over the spots where your pieces meet. Since you mostly want it for cards, though, that shouldn't be a problem.
Scrapbook.com has an informative thread about this very subject: http://www.scrapbook.com/forums/show...p?tid/1527677/
And I did find this link that has an overview of many of the machines out there, which might help. I'm sure there are other comparisons online:

Good luck finding something, Cheryl.
