My Pronto is dying on me (white screen, blank screen, horizontal lines etc.).
I'm looking to buy another device.
I love the big screen, channel logos and macros.
Is there another device with that level of customization?

Consider picking up a Pronto Professional TSU9x00 remote and RFX9x00 extender used on EBay. Can't go wrong. There is no other conventional DIY remote control solution out there which can even come close to picking up where your TSU7000 left off. The Pronto Professional line of course is a major upgrade from the Pronto NG line and with PEP v1 there won't even be a learning curve for you to deal with out the gate. You'll be able to import your current PCF file and have full functionality, then begin work updating your graphics and programming to take advantage of the additional hard buttons and so forth. The Pronto forum section here will be an invaluable resource for you as well. Another option could also be to simply pick up another Pronto NG remote. I picked up a used TSU7500 remote and RFX6500 extender on the cheap last year in mint condition. If you keep an eye out there are great deals to be had on EBay.
