an 850 w/mrf300 will do it. you need to have a ir flasher to each tv with ir on the remote turned off. have the remote route the signal via the ir routing feature of hte 300. ie let tv1 be emitter 1, tv 2 emitter 2 and so on. will work like a million bucks only cost less. The mrf400 might just be a worthy upgrade if it's in the budget.
you'll also be able to control identical cable boxes too.
