Hi. I recently purchased a SHAD SH-33 Topcase from Belden Motosport (for $136.95, with a silver top) and a Topmaster Kit for my model People 150 ( kit # KOPP15ST, which turned out to be two flat triangular pieces of thin metal, for $14.95). They didn't really work for me...too flimsy, so I drilled four holes through my luggage rack (the one the scoot came with...it's hard plastic) and attached the topcase baseplate directly to it with four nuts/bolts. Works like a charm!!
I would suggest this method to anyone who gets a topcase for their People 150 (mine's a 2009). The SH-33 easily holds my large full-sized HJS helmet, plus other smaller items. This 70-year-old New Hampshire boy will gladly answer any questions about this post at jofour@myfairpoint.net. Man, is my scoot ever FUN to drive! Have a nice day.
