The Yaesu FT-8800R is also a good choice, but cost a few bucks more. Many guys on this forum also have that unit. But they are all great, and it really depends how much you expect a radio to do. I really should have gotten an lesser unit and saved the duckets, but the radio is a keeper. It also requires a USB tether and software to program it. More $$$
This year will be the first year that I will take it out on the Plains. Buy according to you budget, and even good used 2m/70cm unit can be had for $100. More than that, the antenna is the essential item to any decent radio setup. Don't be buying a cheap or inefficient antenna. That is one area where spending a few extra bucks will prove to be money well-spent. If you are a Ham, then you know that antennas are everything and radios are somewhat secondary. If you end up spending $120 on the antenna and $100 on a used radio, that would be a decent plan - IMO. Then, if you grow out of that radio, you will already have an antenna that will be able to max it's capacities to the fullest. The Diamond antenna is xlnt; get the one that gets the most db gain. Worth it...
