My first GMRS HT was a Baofeng UV-9G. Not stellar, but the price was right and the radio is decent while I was learning. After I spent some time with it and learning not just its features but GMRS practice/theory/etc., I bought a Wouxun KV-935G Plus and have been very happy with that.
As others have said, if you are looking to just have conversations with folks you don't know, that is more of a H.A.M. thing. However, if you will make or already have associates using GMRS, then have at it and enjoy!
