Seems I'm getting nowhere with my original question so... screw it, I can get it for $1000. The dude wants $1500. But I know I can get it from him with $1000. So, at least don't tell me "yes, it's a steal" or "no, way too expensive" without a few arguements to back it up. Hit me !
You were asking for buying advice without giving us the most important part of the equation. If we said it was "worth it"... and you paid $10K... we'd all be fools. It's "worth" is what you are willing to pay, and what you will recoup out of it over a period of time.
What does "worth it" mean to you? Are you happy with a potential to recoup your capital in 120 days? 180 days? 365 days?
Is it worth $10K? Sure, if you are willing to wait a very long time. Is it worth $2K? Sure. Is it worth $1K? Yeah, even better than $2K.
