This is the second time I've been a little confused by your comments on the D-Link.
Let's get rid of the question below first.

When set to be a repeater, the D-Link APs are operating in WDS (Wireless Distribution System) mode. There is an Orinoco whitepaper about this; but since I don't have the link handy (google it), the short of it is that WDS is a proposed standard to handle just this sort of thing. Unfortunately when implemented in a single-radio system, it does cut throughput roughly in half.
I feel its not necessary to go for REPEATER mode, thats indeed reduction in bandwidth. Best alternative is to put that AP in AP mode itself and retain the same ssid as other one. I have tested "handoff" for DWL-900AP+ and its no problem. The reason for going to REPEATER mode is to increase the AP coverage area, the same is acheived otherwise also.
As written, the above seems to indicate that placing a second AP without an Ethernet connection will "handoff" traffic to the first AP; I assume rather that you mean that two APs with the same SSID and Ethernet connections will "handoff" a wireless client.
Fine if you have two wired connections; if you need to very cheaply spread a wireless zone over a large area without Ethernet, no go.
The D-Link version of WDS is relatively poor; Mac's airports are fairly good, but require a Mac to configure (go figure); our choice so far is Buffalo products, which mix low price with reasonable performance: $30 more for a Buffalo AP more than makes up for my time restarting a laptop to get correct association.
I will leave to the reader to note that the bandwidth reduction is based on the throttle of bandwidth available at the central AP and to reconfigure equipment to avoid this.
Cisco/Orinoco AP-2000s also do this, and have a lovely two radios to boot. I see 60 of them for $169 on eBay, so choose your cost/performance (2nd PC Slot use required to lower the bandwidth problem).
Finally, if anyone has experience with other WDS equipment, comments appreciated.
