I am running a KG-1000G. I went with this because I could remote mount the faceplate, its 50watts, and I am a big nerd so I could mess around with all the features. Here is my install thread.

I have previously run a Radioddity DB 25G, which I really liked, but was a pain to set up. It is now the base-station in the house. I got it for the quad monitoring, but that's a little much.

I also used to have, and really liked the Midland MXT-275. This one puts all the controls on the mic, so you can stash the body. It's also 15 watts, so it doesn't have to be hardwired into the truck.

If I was a new GMRS user starting out however, I would probably start with a cheapie handset and play around with it. I have and use the Radioddity GM-30. It's cheap, repeater capable and pretty easy to set up and use. It would be a good way to see what the GMRS usage looked like in your area. Lots of good choices to mess around with in this price rage though.

If I was going to go with something for the vehicle for a new user, I would probably get the MXT-275. There are better radios with more features for less money, but the 275 is easy to work, easy to set up, and doesnt make the vehicle cabin look like a radio shack. This one is pretty popular with the off-road crowd for a reason. You can probably find a used one on fleabay pretty cheap, especially since they put the 575 out and lots of folks are upgrading.
For the record- more power does not equal more better in the GMRS radio world. Line of site and terrain masking will effect your range way more than anything else. Once you get north of like 15 watts or so, they are all pretty much the same. I am aware that I mentioned part of the reason I run the radio I run is that it was 50 watts, but i'm used to being a hypocrite ๐ . Honestly, I would be just as happy if it was 20 watts or so, and I would probably get about the same performance.
