Welcome to the forum!
Yes, Inkscape works with....I'd say most if not all graphics tablets. We don't keep a list of those. Whenever you buy it, just ask the seller how much time you have for testing, before it's too late to return it. It seems like it's usually 30 days, but you should always ask, to be sure. Of course if you do have trouble, make sure you troubleshoot it with us first, before you return it.
If they won't let you return it, I'd say they probably aren't a reputable store. If you're looking to buy a used one, off of ebay or craigs list or the like, I would suggest to avoid that. I've never heard of anything good from those.
As far as I know, Inkscape doesn't work with the ipad type of tablets, yet.
