I just got a new Bosto Kingtee... well, that's not entirely true. I found it second-hand on Marktplaats.nl at a very deep discount.
I had been aiming for a used Cintiq 21, but all the ones I found were roughly 1,000 for a broken stand or a scratched up surface. The Bosto on the other hand was in like new condition for about 400.00 US dollars. It had no stand, but that was okay. I ordered a used ergotron monitor arm off eBay for it for about 45.00 US dollars.
So far I like it. It has taken some getting used to. The colors are a little off, but certainly brighter than my old Cintiq 12w. It's easier to adjust them through the graphics card
