parts for a bagger for a craftsman

I have a older craftsman rear engine rider with a 30" deck,model number 502.255060,and i need the clear plastic tube for the bagger,but a cant find the model number for the bagger.the tube is the one that the leaves travel up from the deck to the bagger.its very brittle,and when I grabbed the handle on the tube to unplug it,the handle pulled off of the tube,now theres a hole in the tube,besides its so brittle it problably start crumbling.i called sears parts direct and they want over 80 dollars plus shipping for one.i didn't know if theres a place that sells cheaper parts than sears.i don't know if its a craftsman bagger or a generic one.
