Williams Flash is also a great option. They made about 20,000 of them so they are easy to find and a fun, cheap starter pin. Williams Blackout is also very fun, but to be honest, this era created some of the greatest games of all time. The titles worthy of ownership are nearly endless. See what is available and then make a decision, no need to hunt down specific titles yet.

Beat me to it.

If multiball is a necessity, which it shouldn't be for the era, you need to seriously look at Space Shuttle. It's a game that just never gets old and is everything great about the 80's in one pin.

I'd suggest going a little deeper into the 80's and maybe checking out High Speed, Pinbot, and Grand Lizard. These games all have fun multiballs and you should be able to find them in your price range.
