I like 17 m. Polite people and not suseptible to contests. 20M is good for SSTV and psk31 though.

There has been an issues with repeaters that automatically ID. There have been situations where NOVs were issued for violation of this rule: 95.7 Channel sharing.(a) Channels or channel pairs are available to GMRS systems only on a sharedbasis and will not be assigned for the exclusive use of any licensee. Allstation operators and GMRS system licensees must cooperate in the selectionand use of channels to reduce interference and to make the most effective useof the facilities.A term: "channel camping" was created to refer to those who would send an ID automatically. Supposedly, this would deprive other users use of the frequency. Since an ID is not required, it could constitute a way to show "ownership" of a frequency. Just putting that out there.... No worries here either way.

Typically, in that case, when looking up the FCC ID on such a radio, you would see a Part 95(a) certification as well as a Part 90 certification. If it doesn't have the part 95 certification, it's no good... unless there is some sort of grandfathering in, prior to certification rules?

GMRS and MURS are entirely different radio services. Any type of cross-communication would not be allowed. The Part 90 commercial services are also different radio services. No radio service can intercommunicate with another. Lisenses in one service are not recognized or legal on another one.
