OHmm, I thought that price was pretty good without all the add on stuff.
I don't have pricing info on 3com and cisco but I thought they were considerably higher.? I know attigen is. You don't have to use all the extra stuff.

The reliability and redundancy are always a concern on a new system, but then again I've had 3 R6 Avaya fail on me this year, so that's not exclusive to new products.
