D-link DI-614+ here!
I have only great things to say about it! Works great with all different brand of cards I have tested with it! Also you get free firmware upgrade to make it work at 44Mbps with D-link cards! I recommend the D-link!!!
I had Edimax wireless router bfore, and that was a piece of crab! It did not work flawlessly with any card. It would loose connections every 10-20 minutes and would need to be restarted to get it establish a connection. It did not work with either Compaq or IBM integrated Wlans at all!!! Whatever you buy, don't get Edimax!
