Talk about a bargain... I'll keep my eye out. My trigger finger gets itchy though, lol.3 of 4 of my black gunmetal putters were bought used for $125 or less and there is not a single ding on any of them. Definitely have to be patient though to find the right one for the right deal.
Any club fitter, or large golf retailer that does club repair, can fit the length and lie for you. I do my own length adjustments. Golfsmith in Atlanta has adjusted the lie to 69 on several putters for me.
