If you buy the SUP32, and need full routes, you'll be upgrading (if 
possible) or replacing them with SUP720-3bxl's in probably 2 years or 
less.  This is bound to make you unpopular with everyone other than your 
cisco gear supplier and/or sales rep.

SUP720-3bxl is the only 6500/7600 supervisor that makes sense at this time 
if you plan to carry full routes.  Also, I recommend maxing out the RAM 
now (1gb each on the sup and msfc).  With a single full view, ours eat up 
about 200MB each on the msfc and switch.  And plan to get big CF cards. 
IOS images for these things can be huge (>70MB each).  We're using 512MB 
CF cards.
