Solid Bali for sub $100
Marshall B.
Good Bali for sub $100 price.

A bit shorter than most standard Bali's but flippablility is not compromised due to balancing and weight.

I am taking a look into larger models, however, as rollovers are a pain.

The only gripe I have is the latch becomes loose almost immediately.
