So I'm interested in getting a new graphics tablet, something high-end. Problem is, I wouldn't have the foggiest clue which one to choose! If any of you have the minutes to spare, I could really do with some advice (or you can just ram a specific model down my throat!).

A few details:
-Money is no object. I want to get the tablet that's perfect for me, even if it's super-costly, or only slightly better than a much cheaper option (though I'd like to know what the choices are).
-I use a PC, not a laptop. Windows 7 in case it matters. I usually only use one monitor at a time.
-I'd prefer to avoid a tablet that would involve further hassle, such as having to buy other peripherals or mess around with complicated drivers.
-USB-powered is my preference. I'm not a Bluetooth user.
-I'm aware of extras such as a mouse, programmable keys, etc, but I doubt they'd appeal to me. I'm happy to use my normal keyboard and mouse, I prolly won't care if the tablet has such features.
-I probably want a tablet that has its own screen, and for it to be quite a decent size. A screen only a handful of inches across sounds kinda boring.

That's about it. You guys have a lot more art experience than me, so any help you're willing to give is much appreciated!
