I did a search on the internet and the only place you can buy these is on eBay!??
That's kind of weird. Can you return it for full refund?
I'd say double your budget and get something reputable.
You want to spend $70.00 and be disapointed in a POS . . . or get something usable for years?

It just looks too good to be true. None of the sporting goods stores have it. Be careful of eBay stuff. I sell on there a lot, but rarely buy anything.
