I've had Zyxel 85s for the last two years. They have been reliable (only three restarts required in that time) and trouble-free. The throughput I get is 16Mbps.
I would examine a few more reviews about the 200AV results. From what I've read 65Mbps is what you can expect. That's not bad, all the same. I haven't bought them yet as I am buying a house where I may lay nice thick conduit. In addition, they are not backwards-compatible, so I'd need to shunt two of them through a router.
Go for it. My mail/torrent/fileserver lives on an NSLU2 in a cupboard with a few disks and the wireless router for company.
