Feidaxin u Feidaxin FD-150 A/450 A Programmable Handheld Radio The Feidaxin radios are from China, are very low cost (around $75 with shipping), and I'm hearing great things about them from Agoura Hills CERT and others who have tried them. These are not feature-full radios, but are more than enough to get you on the air and talking! So far I've only heard about their mono-banders (2 m and 70 cm), but they also have a dual-band product. Availability is only through small shops and e. Bay, so not something you can get by popping down to HRO or Jun's. A good sturdy radio with excellent value. You might be able to get a great deal by ordering in quantity, something you won't find with the larger retailers.
