I can definitely find a used 850, but I'm concerned I may not be able to get the software to program it based on what I've read where people say they can't get it because they didn't buy it from an authorized dealer. Can the 850 be programmed by itself like the MX500 can?
You should be able to find an authorized dealer to pass over the MX850 program when you buy the remote. It still uses the stand-alone program, not CCP.
What would I be losing if I went with a R50 instead of an 850?
No RF in a R50. You may consider the MX450 that does have built-in programming and RF.
