You should check your local golf kart shop, they usually do maintenance work on fleets of golf karts and have a large inventory of the T105's. Usually quite a bit cheaper as well since they move so many of them. Buying them on the web can be a bit more expensive plus you have to ship lots of weight..
I can usually get them for 15-20 bux cheaper than anywhere on the web and I simply load the truck and take them home.
Hope that helps...
