Wacom Cintiq - To Buy of Not to Buy

Real tired-like. So I'll babble on about techno-crap.
I'm thinking about getting a Wacom Cintiq tablet. A Cintiq let's you draw directly on your screen (as opposed to the Wacom Intuos tablet which is more of a fancy pen-style mouse). As you can see from the picture above, I already work wonders with the Intuos. Imagine what I could accomplish with a Cintiq!
Here are the issues:
Le Cintiq is freaking expensive. As in, "Dang, dude, that is really expensive." The 21" Cintiq is $2000. $2000 is a lot of money. As in, "Dang, dude, that is a lot of money." The 12" Cintiq is $1000. This is still spendy, and most people say, "I love the 12," but if I had the money, I'd get the 21."
Hrrghl.
Buying hardware can be a big disappointment. You've probably been there. "Wow, this new Macintosh laptop allows me to open files and run programs. Unfortunately it has not made me more like Ghandi, Einstein, or the Dalai Lama. Hell, I'm not even more like John Lennon or Yoko Ono. Damn their sexy industrial design and black and white advertising campaign."

Some hardware purchases are good, however. I've liked my 22" Acer flat panel monitor, though a big part of its appeal is that it was only 230 bucks. No Apple Cinema displays for me. My Intuos tablet has been the most trustworthy piece of computer hardware I've owned--I've used mine for about 6 years now. It's outlived numerous computers, scanners and cameras, plus I use it every day. So, I think I'll stop annoying myself (and more importantly, you, dear reader) and just get the damn Cintiq.
