If you want to stick with Part 95 certified radios, recommended for now, your choices are a bit limited. You have two routes to try, new or used. The prior posts cover the new more popular, and cheaper, Chinese radios. The second are the older used LMR, Land Mobile Radio, the type you see used by factory workers, security guards and some police and fire departments.
My personal experience is mainly with Kenwood radios. The software is normally fairly easy to find and the accessories, battery packs - charger bases - speaker microphones - spare antennas - programming cables etc. are easy to find on line new and used.
My top pick for everyday carry is either the TK-3170, or the version with trunking (which you don't use on GMRS) is the identical looking TK-3173.

A radio with more channels and a few more features is the TK-3180.

The above radios are analog FM only.
If at some point in the future you think you might want to try Armature Radio the above can be "pushed" to operate down in to the 70cm band to cover the repeater section there.
Also there are some radios that include various digital voice modes, currently illegal on GMRS, in addition to the typical analog FM mode. A few of these are also Part 95 certified, for FM use. They also cost significantly more money even used.

If you don't care about Part 95 certification there are a bunch of Part 90 radios that can be used. Just be warned the FCC might not be enforcing the rules when Part 90 radios are being used, but that could change at anytime. Keep that in mind.

And then there are the non US radios that don't even have a any FCC ID or certification. They were never intended to be sold here but can occasionally be found for sale. They are however perfectly legal to use on the Ham 70 cm band.
