Check out igearlist.com for a free outdoor classifieds listing where you can buy or sell new or used outdoor gear, including disc golf shwag. As the site is brand new there are not many posts yet.
I am actually looking for used baskets or any good disc golf bags so if you have one to sell, post it up there and I'll check it out.
For disc golf, you can either search or visit the "Rock and Trail" category and then drill down to "disc golf". They also have a customized Google search engine that only searches known outdoor gear sites.
if you use this site as a link to buy new outdoor gear, you will be helping benefit a featured outdoor non-profit, Healing Waters.
This is run by a few Bay Area local women who take CRAZY international adventures and have a fun blog section.
Once again, http://www.igearlist.com
Happy discing. :P
