Pricing is the hardest part of scrolling if you are selling products. Just remember some pricing will vary by region and even by venue (show) in a region. I am sure they will sell fine at $35 in the suburbs of DC, Atlanta, NYC, Philly, London, etc but in my part of rural USA $20-$25 is the best I can do for pre made and $25 -$30 for custom.
This is why with the premade I use 1/2" stock and stack cut 2X.
