Another poster already replied, but I'd like to add that for almost
all application, you only need full view, if you plan to sell
transit with full view.
 In almost all applications, which I believe this application
might represent, money might be better spend on box that has more
performance that FIB space.
 You could take default route from two BGP providers, local-pref|med
the one you see as your 'primary' provider, and then leak
good (europe|usa|whatnot) from the other provider, that out-performs
money|latency|capacity wise on those destinations.
 If your transit providers don't provide meaningful communities
(or their upstream) and you don't feel like fiddling with as-paths
or prefix-lists, then I guess paying the premium for full BGP
table _and_ good performance or accepting on using 'good weather'
router in border without e.g. hardware linerate ACL are remaining
options.

Thanks,
