I ended up with the Progressive Industries PT30C 30 Amp Portable.
I didn't want to deal with the potential of somone doing poor work and I don't know electrical systems enough to install a hard-wired device. I'm a DYI guy, but have my limits.
But I'm happy with the purchase. I really like the bracket on the cord, so I can lock this up. Plues I bought some adapters, so I can use the Progressive when I'm hooked up to my 15 amp at home or abroad.
Thanks for all the good information.
