Have you looked at the newer spreaders? http://www.newerspreader.com/details.htm
They've come out with a larger size which was my only problem with them originally. I'm not sure if they are cheaper than the Frontier spreaders. I don't remember what I paid for mine But its seems the newer spreaders are cheaper.
I hit auction sales for a year or more looking for one but they were always the humongus ones.
