Confooseld: Thank you for the kind words.
finneganswake: A: About a buck thirty-seven.
Seriously, I prefer not to discuss financial matters publicly but I'm sure that if you do some quick calculations on the commercially obtained goods, you can get a rough idea.

B: What size.
Although, upon further thought, acrylic may not be best for comfort.
Thank you.
