Precious little.
No.
Precious little.

I'll not hold my breath. Once made these things rarely get replaced. We
made a set of these for someone else once. Before starting the project I
tried to estimate what they would cost--I was shocked. And I didn't
overestimate. No, not at all. Once you figure up what you have invested in
yours--planning and building time, materials, assembly time, etc.--you'll
be shocked as well.
