My first tablet, which I got for Christmas 2004 I think, was a Wacom 4x5" Graphire3 (these were replaced by the Bamboo line or I guess the Intuos Small or w/e they are called now). I had a couple of those because the pen in the first one died after a couple of years and it was cheaper just to find another one on eBay. It worked ok but it was super tiny and not very sensitive (512 levels).
In 2012 I replaced it with a Monoprice 9x12" tablet, which was much more comfortable to use and more sensitive (1024 levels, comparable to the Intuos tablets of the time). It was great and still is really (I still have it in storage; it didn't break), but I replaced a year ago with a Monoprice 22" display tablet (like a Cintiq but way cheaper), and the driver is a little quirky, but I love it. This one has 2048 levels of pressure sensitivity.
By quirky I mean that I have to plug in the USB cable after the computer is already on, and sometimes it'll kind of "pause" for a moment, but I just have to wait it out. I don't have any serious problems with it, nor did I have any really with my older Monoprice. They make good tablets. Both have been far more durable than Wacom in my experience.
Edit: I also have an original Surface Pro from 2014 that I have used for art. It's nice but quite small, but it was my only computer (and only art machine) for a number of months when my computer had died, and it's good for sketching or w/e.
