Jeff, I have made and sold a few and I base the price on what material I am using - I have sold some @ $15.00 up to $35.00 - Some other here have sold some as well and I am sure they will chime in soon
I've been offered too much and let them go for too little
Always a tough topic. You have to make ut worth your trouble yet be able to move them.
There are so many variables - my lowest price to break even was around $12. And that one actually was one of my favorites I've made.
Less than that and I'm paying them to take one.
I am also in the minimum $15 camp . Typically I charge $20 for a nice piece of wood but more like $30+ for spalted, highly figured or unique shapes . I always use Ruth's stoppers http://www.torne-lignum.com/ . To me they are head and shoulders above anything else I have seen or used :icon_thum
