Both radios are UHF and cover pmr446,they are the only two mobile uhf radios that have pmr446 on ebay,both are under £150,the Anytone AT-588 is a new radio that's not been out long so i can't comment on it but the yaesu ft-1907 is a nice radio,if i was starting out on pmr446 i would buy it.
Here is the links to ebay to buy them ANYTONE-AT-588 Link Yaesu-FT-1907 Link
Don't waste your time with crap handhelds that only get you out a few roads and away,buy one of the radios above and get a base station pmr446 antenna to go with it and get out for miles.
