Honda 150 or 250cc dirt bike?

I'm 5 6" 130lbs. Would a 150 or 250 work better for me? I'm going with honda as well.

The 150 would be a better starter bike if found used, but there's an intermediate step from the 150 to a 250 and that is the CRF 230. The 230 sits a little lower, seat-wise, than the 250 and close to the same power.

Nothing against a Honda but Yamaha offers the same sized bikes at a slightly lower price-range.
