Like all wireless and even hard drives, determining which is "best" is a futile exercise. No matter what I or anyone else recommends, someone, somewhere will find it intolerable.
So with that caveat in mind, the best "value" available at the moment (imo) is the ZyXEL WAP3205.http://www.newegg.com/Product/Product.aspx?Item=N82E16833181119
I've been waiting for Newegg to drop the shipping charge over the past few days (they often do), but so far no luck.
It can function as a WAP (wireless access point), WDS wireless bridge, wireless client bridge, or wireless repeater bridge. Supports wireless N, comes w/ two LAN ports (presumable extendable w/ a switch), even supports multiple SSIDs for separate secured and guest access. A lot of features packed into one device. You can easily pay $70 or more for a simple Linksys wireless client bridge.
Normally I prefer dd-wrt compatible routers for all my wireless bridging needs, but many ppl don’t like the idea of dealing w/ third party firmware (but it’s a terrific solution). One of my favorite dd-wrt compatible routers is the ASUS WL-520GU.http://www.newegg.com/Product/Product.aspx?Item=N82E16833320023
But it’s only wireless G compared the ZyXEL (N). And the ZyXEL is only another $7-8 after shipping. In fact, I’ve seen the ZyXEL selling for as little as $31 shipped (after rebate), well below the WL-520GU. There’s just no better “value” in wireless bridging right now than the ZyXEL if you confine yourself to NON dd-wrt compatible routers. It’s just a matter of whether you wait in hopes the ZyXEL drops even a little more.
