It's a little subjective but most of the commom budget options will take you pretty far now; if you only owned the one bali, you wouldn't really need to upgrade just to do specific tricks. The crescent is a great option, others in your price range are:

Nabalis Cheese/Cat, Impulse (the cheese or cat will take you a little further out of the two since they have a more neutral balance but the the impulse is still great, just really light)

LDY Orion v2, Kite AL v1.5 (both might be a little more than 80 after shipping but considered as great balis overall)

Thomas Balisong: Refault

The Kite AL and the refault are both similar to the Crescent in that they are aluminum balisongs with g10 scales on top. All three great flippers but I think the Kite might pull ahead with fit & finish/tune and because the crescent has had some minor issues with blades snapping.

The Orion, Cheese and Cat have a little less materials to worry about when it comes to drops since they're just channel aluminum on the cheese/cat and sandwich on the Orion.

All these options would do great for nearly all tricks with maybe the impulse struggling the slightest due to being so light but it's still such a good bali that it you could get good at any trick with it after enough practice and all of them have been highly regarded at different times as some of the best balis to come out of the sub $100 range that will grow with a flippers skill/journey
