Answer 1

don`t buy it  , buy a named brand

Answer 2

When I checked the ambicom.com website they list a wl300n.  Matches the description on ebay.  The website sells the device for $39.  

Similar linksys product runs $70-90.

The "fear" is quality.  Sometimes lesser know and less expensive brands are as good as better known product.

That's your gamble.  There is a 14 day return policy with 15% restocking fee.  Not bad.  Reduces the gamble.  Pay with credit card, install immediately, test speed with 2wire.com or similar.  If not up to speed, or if it tends to drop connectivity, decide if you can live with it or return immediately.
