How is it that there are Paddy Wagons available but you can't get your name on it without paying extra? If the distributor has what you want, you should be able to pay for it now and then wait for the shop's order to accumulate to the point where it's feasible for them to consume the shipping costs. If it's a now or never thing, the '07 PW comes with TWO brakes, a fixed cog AND a freewheel. To turn the Flite into the PW, you would have to buy two brakes (40$), two levers (20$), cables and housing (10$) and a freewheel (10$), not including installation. Since you're going to be running it freewheel, at least initially, the PW sounds like a better deal.
Also, if it matters, the '08 PW should be available around the middle of August, give or take a week or two. It looks like this. I think it's pretty neat.
