If you plan on doing just an active/standby setup with your upstream 
providers, you only need to take a default route via BGP from each of 
them.  I have (almost) exactly this configuration running at a number of 
client sites on a variety of routers.  A 2801 will handle this with no 
problems.

Rather than having I'm assuming static default routes internally, run IBGP 
between your two EBGP speaking routers.  Static routes can get messy.

Since you're only talking about a small handful of BGP routes, a small 
router like a 2800 series should work just fine.  Would I try to cram a 
full Internet routing table into a 2800?  No.
