I know Ruckus has been mentioned before by others but I am REALLY REALLY happy with the unleashed Ruckus R710's I picked up (@210.00 each shipped) off the bay. I've been running them for about 7 months on current FW and while I've got some apple devices and I have seen the slow down - but on my GF's various droid devices and her work DELL and personal Sammy laptop the performance and reliability has been really really great.
I ran a cisco 2504 WLC with 3702's until 7 months ago and the ruckus stuff is better, faster, less footprint simpler to manage for "typical use" with VLANS and multiple SSID's.
I've got an old house with lots of additions, Solid walls in the middle of the house (formerly exterior walls), rebar, lots of steel. Put one at each end of the house and I have no dead spots. They're not even mounted correctly, waist level pointing up sitting on tables. Heck I get a 50% signal about 500' away down the street in a neighbor's house. Someday they'll fix the perf bug in unleashed but honestly its been more than acceptable on my apple devices for my use YMMV...
