Prices - discussion thread!

[rocketlily]

It seems to me that the prices on corals and fish have been decided on for this contest. I think all is fair. I would like however, to get clarification on equipment. Here's some assumptions I am making. Can you tell me if these are true or I am mistaken on some things.

1. New equipment purchased - deduct purchase price.
2. Used equipment you have at home, previously purchased- 75% of J&L's new price.
3. Used/new equipment you have at home, received for free - free
4. Used equipment given to you at no charge- fair market value of this used piece of equipment.
5. Used equipment purchased at a very good price - price you paid
6. Shop supplies and/or scrap with no value from work ???

Just trying to get all the rules straight.
