I'm a huge commercial radio fan. Dollar for dollar, they have better receivers and transmitters and stand up to years of use. Very simple to operate and darn near bulletproof. I've had some bad experiences with the cheap import stuff. Displays conking out, buttons and knobs breaking or coming off, etc. Commercial radio equipment is made for decades of use and abuse under stringent business, industrial, and public safety use. There is no other choice if you're serious about having a really good radio.
I'm running a GE MLS mobile radio (made in 1991) for GMRS and its never given me one ounce of trouble. It just works.
With that said, I can't recommend GE anymore because they're hard to find and harder to get programmed or repaired if you ever have an issue. The company stopped making two way radios almost 25 years ago. Motorola and Kenwood are your best bet and both companies make solid radios. Kenwood is a lot easier to program because getting the software isn't treated like you asked for the NORAD nuclear missle codes. I pay to have my Motorola GMRS radios programmed at the local shop because its less of a hassle than trying to buy proprietary software through the Big M. You can find a lot of Kenwood programming stuff on eBay.
I've had good luck with the Motorola Radius M216 and CDM 1250 units for GMRS. The Radius products are much older than the CDM series and can be purchased cheap. With Kenwood, I absolutely love the TK-890 series, although there are several newer units that are smaller that are very popular with the GMRS crowd. Check eBay and see what you can find.
Hope this helps.
