"RF Extender" is the terminology for the Philips unit that does what you're speaking of. The extender, RFX6000 for use with the TSU7000, receives signals from the Pronto in RF and then re-emitts them in IR. It has a blaster and hard wired emitters that can be attached directly to equipment.

I suggest you give the Pronto a try, now that you have it. For the price you paid you can play with it for some time and still flip it for a profit. I'll second Ali's suggestion to purchase the Ultimate Pronto Guide. I'm fairly computer savy and it saved me many, many hours. The cost is small and well worth it. Add it on to the what you paid for your Pronto and you're still way ahead in the game.

If you are going to utilize the RF capability of the Pronto right away, you shouldn't have to hard a time getting your hands on one of the extenders. I've seen auctions go for and personally paid well over $300USD for your model Pronto and extender.

Best of Luck...!
