Ricin, how does that adaptec work?

Works great, I haven't had any problems with the one I use at work, or the few we have depolyed to some of our stores. It is actually going to become part of a wireless roll-out we are doing over the next few months.

Are there any downsides that you have seen so far?

None that I've found. It is a very good unit for the cost. The version above that with the 4 port 10/100 switch was available a few weeks ago for just $15 more or so, but I believe that was a one time fire-sale type deal, as I don't see them on the site any more.
