Gehl mini

Hi there, I have been looking for a good deal on a mini ex for a while now..... and still looking. I have seen a couple of Gehl machines up for sale recently. One that has got my interest is a Gehl 503Z. Low hours, thumb and a reasonable price, but I am cautious about brand as I can find very little information (on internet) about the machines. Does anyone out there have some thoughts on the quality, parts cost etc on Gehl machines. Thanks. Alan.
