US version of 5045 or 5026....where to buy, experiences...etc?

Would like to know where you can find them in the States, approximate price, any special “bad experiences”, if they can be macro and region hacked, etc.

(My TiVos have been acting up a bit lately, and I just plain will NOT record directly to DVD first…gotta do the hard drive thing as the first step. :iagree: )
