If I had to go with my childhood favorite, it would be the criss cross crash set. It’s simple to set up, but can tend to be loud with the amount of boosters - here’s one off amazon for $50

Damn, they still sell the Criss Cross Crash. If I was a few BL's deep, this thing would be showing up on my doorstep come Monday.
