Well, Crestron or AMX is going to be significantly more expensive than a Pronto..... (TSU3000 BTW) but would be Substantially more reliable.

Are you switching just one TV? Are all your components within one Line of sight? This is the only way a Pronto has a chance of working as its going to send out IR from itself, or from the RX-77 RF adaptor. Which may or may not work depending on how large your bar is and how far apart the TV's are (You may need an RX-77 for each TV)

AMX on the other hand is going to be hard wired to each TV, Video switcher, Source component etc etc etc. An NI-2000 runs about 2000 then you need to get it programmed for your macro. then you need some sort of user interface.... This could be a basic web page or a custome touchpanel.....
