I was in the same tire delima when I began getting my bike back on the road. Had good 15 yr old rubber, if there is such a thing, but I didn't have the extra cash , so....
I opted for a set of the Duro's. At least they were new and cheap. I got maybe 5K miles out of the rear but that was ok. I still have the Duro on the front and have no complaints about it.
