Access Point selection

I am creating a small,  yet true and fully functional (as in assignment of external IP's in a class C block), highspeed WISP for a condo community which will serve roughly 100-150 residences and we would like to do it completely wirelessly.  Aside from the Indoor Cisco 1252, are there any other AP's that transmit IAW 802.11n?  The best solution would be outdoor 802.11n AP's because the tenants actually own the inside of the units and there are no hallways or HOA owned property connecting the inside of the units.  If there are no outdoor varients, could an indoor AP be used outdoors effectively (specifically the Cisco 1252 or some variant)?  Also, if not 802.11n, what are some options for highspeed 802.11x variants with low latency?  Finally, aside from WDS and a mesh, are there any other setups that will allow dynamic routing across the AP's?  IE, if the user wants to walk somewhere on the property and roam between the AP's without losing connection.  I've read that mesh and WDS kill the effective bandwidth--presumably due to the hops to get back to the base.

Note: the core setup for the WISP are two DS3's at 25/mbits with BGP redundancy, a cisco 7200 mxr router, and RADIUS server for authentication.

Very Respectfully,
Phillip

The Cisco Aironet 1510AG is outdoor rated and dual band... in mesh mode they use the 5GHz radio to communicate with other 1510's, and the 2.4GHz radio for client connections, providing maximum bandwidth.
http://www.cisco.com/en/US/prod/collateral/wireless/ps5679/ps6548/product_data_sheet0900aecd803642e6.html is the info page for them... as it shows, AIR-LAP1510AG-A-K9 is the FCC-configured model, and they have many antenna and mounting options listed there as well.

*Probably* those will be upgradable to 802.11n when that standard is ratified, but that's still over a year away.

As far as using the Cisco 1252 outdoors, is there a viable solution for that?  

Also, as stated before "Finally, aside from WDS and a mesh, are there any other setups that will allow dynamic routing across the AP's?  IE, if the user wants to walk somewhere on the property and roam between the AP's without losing connection.  I've read that mesh and WDS kill the effective bandwidth--presumably due to the hops to get back to the base."

Is there much of a degredation in perceived speed when using a mesh like there is in WDS?
Also, as far as the .11g is concerned, how are some radios achieving a theoretical max of 108mbps?

the DS3's are a minimum commit of 25mbits, with a burstable speed of 45.  So basically we have the equiv of 1 full DS3 with redundancy.
