I'm sure a good keen man like yourself could make one if your handy in the shed and don't mind scrounging for the stuff at your local recycle centre.
Then you can use your funds for the purchase of some stainless steel pins and other essentials.
I've currently got one under construction using a square Sistemia spaghetti container pushed inside a short length of PVC pipe.
Will use a small motor and drive it off a couple of 1" shafts mounted on plumer bearings.
Cheers
Pete
