I just purchased two used high end saddles in the last 6 months. First one came from www.mdtackexchange.com
Nicole was great to work with a very knowledgeable. I purchased this most recent one from www.yoursaddles.com and worked with Patricia. She was also great. Both were great with communication, able to answer questions about the saddles I was interested in and helped to guide towards purchasing the right saddle.
I got an awesome Antares in wonderful condition for a great price from them!
Just note that CWD has a $50 restocking fee. I don't think most of the others listed have a restocking fee. Just something to consider if you aren't 100% sure the saddle will work. Shipping saddles for trial can be expensive enough without a restocking fee.
Oh, well, clearly you're not thoroughly indoctrinated to COTH yet, because finger pointing and drawing conclusions are the cornerstones of this great online community. (Tidy Rabbit)
