Well since you already own Iron Maiden (people really should look at collections before answering) easily the best pro “priced” games are:

Star Trek Pro

Ironman

Based on your avatar alone and what you can pick one up for on the HUO market
Spider-Man would be one of the best games you can pick up, amazing rules, one of Ritchie’s best layouts and it’s packed!!

Tron Pro (if you can get one on a pro budget)

Metallica is a fantastic pro but I prefer the cool mechs on the Prem and that left to right orbit diverter on Deadpool is a game changer, Deadpool is Premium all the way with that.

Can’t go wrong with Star Trek but the light show on the Premium is awesome and those LED side rails on the LE are insane, wont ever sell my LE unless I reach 5YM wizard mode. So I’ll likely have it until the day I die
