If you're multihomed to the same provider, I wouldn't even bother with
getting an ASN and running BGP at all.

I assume they are providing your IP space as well...if so, let them
announce the route, and let their internal routing policy decide which
circuit delivers the bits to you.

Then, just configure two static default routes, to the two serial ports of
your upstream. In this scenario, you're current router should be fine.
Buy your router used, you're wasting your money otherwise.

To answer your question directly, there is essentially no benefit to
taking full routes from your provider from each location.
