Not many options when I bought mine, only one that I knew of and that one was 450 bucks, so.....decided to make my own. Bought the 1/2 windshield from a sale at cabelas for a larger machine for 30 bucks and cut it down to fit the contour of my machine. Then bought a 24" x 48" pc of lexan and trimmed to fit my machine then added a 48" SS hinge. All together I have 200 in it. Now there are a number of companies that make windshields for the 450i just do a simple internet search and you will find them including pic and prices.
