Try ebay, I found 10 3COM - 3c-905's for $36 including shipping, I think they are unbeatable.

Anyone have a good source
The switch I am looking to replace is at my core, tying my APs together,
and to the main router.
The one I am looking at/leaning to is the Dell Powerconnect 2708. Its
Web manageable, and has some pretty impressive features, including
broadcast storm control VLan tagging, and port mirroring.
BTW, this is what gets lots of people in trouble. Quoting 16-18 mesh nodes
per square mile may be a correct number in AZ or TX. You may need 3 times
that in my neck of the woods here in NE USA. Even more where interference
shrinks cell sizes. Be cautious John. Brad

Here in Atlanta, Metrocom reported that it took 4 times the average
number of nodes to provide coverage. Technology has changed a good deal
since then, but then again they were also using 900Mhz, which has a lot
more success with our pine trees than 2.4Ghz.

I haven't read your summary yet, but would like to chime in a bit on Mesh...
When the DoD developed TCP/IP, they built it to be robust under war-time
conditions. This means fault tolerant, rerouting, change-over, change-back.
It would wonderful to hear the Mesh scientists (not sales people)
The internet is the largest mesh network in operation today. However,
there is no comparison to internet routing and redundancy to that of
private network routing and redundancy. The internet is so huge that
smart routing decisions can only be made at the edge. With a private
network, the size

It would be nice to see this in a word

Matt,
Are these actual costs?
What is the coverage area?
Thanks,

I used street pricing for the radios in question, but certainly didn't
cover pricing on any other items that would be required. Coverage area
wasn't taken into consideration as it has no bearing on topology.

Welcome gang. Glad to see all of you.

There is a very big difference from fiber mesh and wireless mesh.
Wireless is classicly a bunch of HDX links
where fiber is PtP links. Your example doesnt make it clear that the
difference is what cause's 802.11[a|b|g]
mesh suck and fiber/copper mesh's not suck. The solution is multi
radio
My example used wireless P2P links, which has no inherent weakness over
fiber P2P links from a topology point-of-view. It would appear you are
falling into the same trap as others by forcing mesh to be something it
is not. Mesh is just a network topology; no more, no less. Sure it is
possible
Jeromie,
You raise some good points... and here are some more differences between
Matt's fully-meshed WIRED network example and the real-world conditions
under which WIRELESS mesh networks are so often deployed today.
1) REROUTING - Only a node failure or a high peak traffic load would
