I Really like my Pronto TSU7000 remote, Much more than any of the Universal remotes ive used. Its alot more flexible, attractive, and has a very nice color touchscreen. Only downside is the volume and channel buttons on the side are quite small. And unlike the TX1000 you can use it with one hand easily. I have read some bad reviews on them with people saying they break easily or something but so far so good for me.
Theres certainly nothing wrong with the MX900 though. I program about 3 of those things a week and we havent had any problems with them.
