I don't know about Hiuion but I had an Aiptek, which is a rebrand of a number of the Taiwan brands and the Wacom technology is so much better, as are their updates. I had a Wacom Graphire in the 90s, an Aiptek in the 2000s, I the upgraded to a Wacom Bamboo in 2009 and now I have a Wacom Intous 4. The Wacom's technology is so so much better than anyone else. My first Graphire. was as small but my other were medium. I would recommend the medium. I would also recommend used on eBay, where I got my Intous 4 for just over $100n with shipping. I think using a tablet is much better than a mouse but you need to get used to it, it is a bit different than drawing on paper. Give it time and you'll definitely appreciate the difference..
