Similarly for the Ruckus R610 AP I mentioned: Those APs were a grand new, but you can get them for a bit over $100 on ebay. Linus Tech Tips did a comparison of it with other consumer units, doing heavy multi-device streaming, and Ruckus was the clear winner.
Yes, Ubiquiti looks like a good value and they make some very interesting products. I've used some of them to great effect over the years. But my experience with the NVR and cameras and switch and Cloud Key has been relatively bumpy. Enough so that I'm ready to ditch the convenience for up-front loading and hopefully day-to-day more realible.
Have you looked at the power consumption of the switch? I've run some enterprise gear at home in the past (my favorite was the E-450 Sun server which an ex-employer gave me for free), but when I started paying for my own power, I found that even if the hardware is free, the power consumption makes it expensive.
Most recent version is a couple years old, but it was EOLed 3 years ago.
Ruckus firmware seems to be downloadable from their main product page for the R610, updated a month ago.
Re power consumption, it looks like the Aruba pulls around 50W idle, and the Ubiquiti pulls 29W idle. Of course, if I can get rid of the second switch I've been running because the Ubiquiti keeps blocking the Google WiFi ports, that brings it even closer. :-)
Can you get free firmware updates from Aruba or do you need a support contract?
