Who sells an affordable(read cheap) cane blank of decent quality?

I've built a few graphite rods and would like to take on a cane for this winters project . I've never owned cane before but I just love the classic look and the history behind them . I can't afford to lay out the bucks to buy a quality prebuilt right now and I would like to be able to say that I built my own. I think building your own rods really increases the pride of ownership.
