Do you currently have a Wireless AP or Router already?
I have seen the d-link bridge and know it works.
I prefer Linksys as they are sticking closer to the standards where d-link does their own thing and can cause issues when trying to connect using a non-d-link device.
Also when looking at wireless it is best to stick with 1 brand.
FYI if you want a good AP/Bridge/Repeater/Client I would get the Linksys WAP54G it can do everything but serve as a fully functional router. It doesnt like the d-link when trying to bridge, but i found a way around it. I use the WAP54G in AP Client mode, and what that does is make the xbox look like a wireless device to the d-link ap, meaning if you look at the connections to the router/ap it shows the MAC of the AP and the MAC of the xbox.
So if you have no wireless yet look at getting a
WRT54G for your Router/AP and then get a few
WAP54G's or you could get the actual gameing adaptor, the
WGA54G then you are sure to have no problems as that is the new version of the WET11
As for cheap, I would get the DWL-810+ if you are going to get a DL-624 which you can get for just over $50 at justdeals.com then you are sure to have a match + you would be runing at 22Mbps. There is also a DWL-G810+ but is is about $99 but then you could have a 108Mbps wireless bridge. hehe
The WET11 will always cost more due to the fact it is the standard for a wireless bridge.
