I have and it's close. I guess I have a hard time dumping so much money into a remote... before I do, I gotta reconcile it in my head. I think for $250 you should be able to get everything a typical system needs.
Define "typical system".
$250 won't usually get a remote that does macros, it'll be basic, might be only activity-based and that alone can be a huge PITA. The MX-810 is one of the less expensive URC models but because so many installers and programmers complained that it doesn't program the same way as all of their other models, they came out with the MX-880, which looks the same but uses the MX Editor. If these people had paid attention or gone to training, they would have known that it uses a setup Wizard, but that's another matter.
Personally, I think too much emphasis is placed on the custom graphics. Basic remotes do not need them, IMO. The MX 350/550/650/750/850 are monochrome titles and they work fine but the models in that series use serial communication, which makes them less popular. They work great, though.
Keep in mind that if you buy a URC online, it won't come with a warranty because they don't authorize ANYONE to sell online.
IR and RF work fine with discreets and even if a piece of equipment does toggle ON/OFF, there's usually some kind of work-around. In the case of the Scientific Atlanta 8300HDC, it's a matter of going into Settings, look on the left column for Settings (not along the bottom), Power settings and select On with numeric. Then, add a command in the power on sequence for whatever Power On channel is acceptable. Time Warner uses Ch 0 and 01 for their information, so those don't work. Supposedly, SA receivers will revert to the last channel if a useless channel is selected but I didn't see it happen yesterday when I fixed a power command issue for someone.
BTW- Time Warner and some other providers set their boxes to turn off if they haven't been used for a particular time period and this is why they suck. I wouldn't care if they would enable discreet ON/OFF but they don't, so my opinion stands.
