if it is for company. a bit more expensive should be ok.

i have tried Netgear 624, Linksys G, linksys G with speed boost, Dlink G, Dlink superG, Microsoft G.

amoung these i have tried, i like netgear 624 and Dlink SuperG the best. but that's for overall experience. all wireless router has their strangth and weakness. for example, for superG, it's better to have superG client card to get the most of it. sometimes not stable link with normal G card.

don't use the 10/100 switch on the wireless router. i found all wireless router's wired stitching are quite poor. (compare with 3com)
