  I would have to say my experience is different for cpe stub
  routers for customers that don't need full tables.

  There is no question that at least a 4xxx should be used for any 
  sizable bgp mesh.  However, I used 2500 routers for limited BGP 
  peers at the periphery of my network with no problems whatsoever.  I 
  just fed my IGP routes to the 2500 via iBGP, peer w/ the transit AS 
  and take just ^ASNUMBER$ from them.  Worked well, no reliability 
  problems, no cpu problems.  Obviously this only works if the
  customer doesn't need full tables.  

  If we were talking about meshing full tables, or multiple peers,
  then I'd very much suggest using a 4xxx or 7xxx.
