Whats the best hardware for running XBMC?

[Sidsnot]

I have XBMC running on my PC and im looking for something like an android TV stick so i can run it quick and easy. But i know i can use a Raspberry Pi or a HTPC as well.

I want something that boots up real quick, or i just leave on, that runs HD without struggling, and doesnt cost too much. What do you guys suggest?

A PC is great but you have to wait for load up. For quicker loading go for Jailbroken Apple TV, Android Box/stick or raspberry pi
