Awesome Scanners Unite!

I am looking into upgrading my scanner to an awesome large format scanner . . .  The problem is there are A LOT of potentially awesome and potentially not so awesome scanners out there.  I kinda want the awesome one.

So here's where you come in . . .  Do you have any advice on what scanner I should get?  What have you learned from your own experience?

Do unicorn coasters help?
Thanks for the input!
