I'd buy a fun EM project, fix it up, and go shopping with whatever money is left. I'm partial to Superflite, Pit Stop and Spanish Eyes. That should leave enough money in your bank account to buy a pro new in box if you desire. Or just fill your house with awesome EM games.
If you want to split the cash more evenly, I'd probably do Stargate and something Steve Ritchie. No Fear? That leaves some money for upgrades.
