This great case is on sale at Amazon for $79.99 with free shipping. It has received excellent reviews all around, I don’t think I have seen a bad one yet.

EDIT: It looks like Amazon changed this to Prime only after I posted this, so YMMV if you are not a Prime member.
This normally runs from $100-$110 and has been on the frontpage for $80 AR and $90 w/o rebate in the last year.
Downside is that only the Titanium color non-windowed version is on sale right now, but personally, I like it the best anyway.
