Hi Andy,
If your willing to buy them online, a great site is
www.kaboomfireworks.com. They have an amazing selection and their prices are good. However, a minimum purchase of $150 is required. They also have the videos for some of their selection. My personal pick would be cakes, air booms (the more, the better), and some multi-effects. Try to vary the effects. I hate when people just buy roman candles. Although they're nice, they get boring very quickly. Also vary the color, height, and intensity (well, I'm a bit picky). You might want to start off with air booms, followed with candles and fontains. Then start to work your way up with multis, brazilian shells, flowers, and finish with cakes. Anyways, have fun shopping
