I tried Unleashed vs. ZoneDirector. Unleashed was fine, but I felt like I was crippled from the ZD options. Sorry I cannot provide more info. as it's been awhile and I forget the details. I think if I had maybe 3-5 AP's I'd look more seriously at Unleashed. I'll also share that I moved to the zd1200 a couple years ago from an zd1100, the 1200 is much quicker and has less finicky issues.... could be code maturity but I'm guessing that newer faster hardware had lent a hand in performance and NO issues. My ZD1200's have been up for over a year with no issues, code 9.12 & 14 AP's.
