Welcome Stal8080,
As you're looking for games, be sure to check the market place here for games that are for sale in your area. With today's current pricing, I think you're going to have to be patient to find a 90s DMD style game in your budget. It can be done, but it will take patience.
Now, if you aren't all that concerned about having a DMD style game then you will open yourself up to many other possibilities, such as the Fire! that Waddle has.
Lots of good games out there and once you buy one - you'll buy another.
Dave
