Route-reflectors are the correct way to do this.

I would use route-reflectors with only a handful of devices. Think using 
something with a very fast control-plane like an ASR RP-2 to handle your 
100 BGP sessions, where as soemthing like a SUP720 only has two sessions 
to look after, instead of 99.
