Wifi and arduino please help

Hello,

I want to connect my arduino UNO to wifi, but the wifi shields are way too expensive for me.
Can I also use an Ethernet shield and a wifi bridge to connect my Arduino to a wifi network?
This is the wifi bridge I want to use: http://www.ebay.com/itm/NEW-WiFi-Bridge-Dongle-Wireless-For-XBox-PS3-RJ45-Laptop-VOIP-AP-Vonets-VAP11G-/150932162673?pt=LH_DefaultDomain_0&hash=item2324420871

Thanks for your help!

I don't know the product from my own experience but from the specs I would say this should be no problem.
