In the Y Combinator / Anybots office we just switched to Meraki's commercial-grade APs and they kick butt. Only a little more expensive than consumer boxes and they provide seamless roaming between APs, multiple virtual networks, and seem to handle large loads well. Somehow they isolate 802.11b users on a separate channel (there are still plenty of laptops that only do .b), so .g and .n users get full bandwidth. I think they push .a-capable users onto 5 GHz too. Also easy to set up. It's the first of many APs I've owned that hasn't made me pull my hair out. Recommended.
