Oooohh.... I bought some for my kidlets today, they asked Santa for them, too! I shopped around and decided on the Uniden ones from **** Smith. They cost $99 but they are 'proper' ones with rechargeable batteries, 4km radius and 12 month warranty. They did stock smaller Unidens for $49 (maybe the same ones Kelly mentioned??) but they took normal batteries which the girl said didn't last terribly long if the kids use them a lot. Also thought they were a bit too small (easy to lose) and... well, the girl told me the rechargeable ones were better!!! I reckon the kiddies will have fun with them!
