BSD is a killer machine and lots of fun but doesn't have any modes or wizard mode - it's all about stacking multiballs and its hard and fast. If you like to go through the modes and reach story modes then a Jurassic Park is very cool - the dino is great and the wizard mode is fun too (plus it has a shaker motor). Your friends probably won't like Drac but you'll love it - they more than likely will enjoy JP.
If you have an RFM see if you can pick up a cheap Star Wars Ep kit - it's not the best game around but I managed to pick up an NIB kit for under $2K AUD so it's fairly cheap, beautiful to look at and again your friends will think it's pretty cool. Plus it leaves you room to add another machine so you can still pick up a JP or BSD
