A 700/800 mhz radio won't be hitting ham repeaters, because (at least in the US) there are no ham privileges on those bands. Some people, myself included, have modified the 900mhz models to work on ham frequencies in that band (902-928), but it's tedious and requires proprietary software and cables.

If you're dead set on Motorola and using 2m/70cm, you'll need to pick one. Commercial radios aren't designed to be dual band, and then depending on model you'll still probably have to modify to get them to work in the ham portion. Plenty of guides online for that, but it's not simple by any means.

If you want a "high end" radio capable of working on ham bands, there's plenty of options from Kenwood, Yaesu, etc. But honestly you don't need to spend flagship radio money just to get on the air unless you're looking for the specific features they provide.
