Fuzzy: Wouxon are also decent fairly cheap radios, no doubt. Probably some features better than the bargain UV-5R variants. That said, I have yet to see another radio that gives so much bang for the buck. And if you accidently lose it, drop and break it; it won't kill your bank account trying to replace it, unlike some pricey Yaesu rig. Would love to see someone do a review of Wouxon radios as a comparison.
The stock antenna is okay on the UV-5R, but definitely get a performance boost by changing it out. Somewhere in this thread, I listed the one I bought super cheap.
