Good Wedges for cheap....that question is relative to what you think cheap is...
Here's my idea of good wedges on the cheap;)
Search ebay for Solus RD 4.1's or www.solusgolf.com
I've observed these going in the $40 to $60 range in near new condition. I've owned / played about every major brand / model out there and I'd take the solus over them everytime.
Search eBay for Feel Golf wedges.
I'm not associated with any eBay Stores but a good place to window shop for wedges and more is "globalgolf"
i have a Callaway Big Bertha Sand Wedge i dont use. right now im using an older set of Titleist DCI 981's and a DCI SW. i bought the Callaway to compare it, and the DCI just feels better. The BB is used and needs to be cleaned, which i can do for you, but its in excellent condition. the grips are in great condition, no wear on them, the head doesnt have any chips or defects. if you are interested i can get you some pictures. ive been thinking of putting it up for auction, just havent gotten to it yet.
http://www.warriorcustomgolf.com good cheap wedges, not great wedges. Got a LW, GW and SW for around $35.00. May have to search the site for the promotional ad. In fact if you want mine you can have them for 15.00 plus shipping cost.
