I have a saved search on ebay for the tsu9600 and the tsu9800. You can sometimes find used 9600's for $100 to $125. 9800's are pretty rare, and more expensive. Both have a 640 x 480 display, so one program can run on either remote. Be sure you get the charging dock and the wall wart! The remote does NOT charge over the usb port!

When you compare PEP1 and PEP2, they do the same things, but are arranged on the screen differently. PEP2 does have a database to deal with.

PEP2 does have issues with installing on newer Windows versions. Usually you can work it out. Sometimes the install stalls out, and you have to stop the ProntoDataServices to continue the install. Then you restart it when you run the program.

Prontos are really best suited, in my opinion, for IR control, either directly or with an extender. Although they can do IP control, you have to do the programming yourself at a basic level, using Prontoscript. (Based on Javascript.) Unless you have experience with sockets, http protocols, networking, etc., the water gets deep pretty fast. You could start with IR to learn the basics and add in IP later.

PEP2 will also have trouble downloading to the remote if you have a Logitech wireless mouse or keyboard. It's a Windows thing. Some people have a virtual xp machine in their pc and run PEP in that. Another approach would be an old laptop that runs xp.

There are a number of people on the forum that are very knowledgable and will help you. Lyndell is very knowedgable, and always seems to be around.
