The Summit doesn't get good reviews. I'd recommend against Freeplay as a brand in general, particularly given their radios can't run on regular batteries. Yes, you can rip them open and replace their built-in NiHMs yourself, but do you really want to go to the trouble? (And where do you get replacements in an emergency?)

As for the SDR, why on earth would he want a spectrum displayer? My guess is the OP wouldn't know what to do with one, given the introductory nature of his question. It also requires a laptop, which is the last thing you'd want to have to power (or carry) in an emergency unless you're doing emcomms work.
