*No useable sales or B/Os, using the clean price.

**Yes, the Drill was used to price the Tree, however there were two sales at 90(what the drill was valued at, at the time), so if the sale wasn't used it wouldn't make a difference on it's current price.

Using 86-92.

Two sales, 75-81 Keys should be fine.

Additional Proof/Counter-Proof/Constructive Criticism/Feedback is always appreciated.
