I won't tell you because I don't have much experience yet with gmrs mobiles, but I have two ra87s I'm setting up as a local private repeater (at first) and although I haven't used them I was pleasantly surprised with the quality and feel you get for the price, you can buy the repeater "core" set, just two mobiles and the data cable, usually on eBay for about 300 bucks! But I really want to get my hands on a couple few(or more) of the wouxun kg1000g plus mobiles. There are quite a few more affordable than the kg but I hear it's the "creme de la creme" of gmrs mobile units. I just never, NEVER see them on sale like I see almost all the other brands on sale.
