Although I am not an expert.. Consider this: 
Cisco will tell you that a 2650XM router Retail:$3295. 
	This has the power and RAM to handle a huge route table..

See note above.. Routers are cheap.. I am using a 2621 to multihome..
Default route only.. Ya don't need a 7200 anymore... and with the new
7200 Proc upgrade..... anyway we should not be doing WAN design here.....

Route table size..Assume an end user is multi-homed with ISP A and ISP B
ISP A provides the IP addresses, and ISP A can summarize.. ISP B can't
so routing table size is still gonna grow!!!

NOTE 2: If we use the /8 block to Multi-home, the back bone providers may very well
have the option to summarize the multi-homers.... They, Assume backbone A,
get and more.. All of these go to different Tier 2/3
providers below Backbone A. Backbone A will summarize.. hence global tables don't really grow
that much.. 

Anyway, this is not a routing class either...
