One of the frustrations is that I can't find much of anything online regarding prices on these machines in order to make some bang for the buck comparisons. Any ideas?
A search on e-Bay for "zero turn mowers" will show 90 hits. Some of these are buy-it-now prices on new machines. This isn't the same as pricing at a dealer, but it might give you some idea of the price range of some different machines.
Happy hunting.
