Yep, I just had to have one of those Hot shoe levels when I ran across them.
I do use mine sometimes. It's handy, keeps your mind occupied worrying about losing it,
dropping it, scratching it up carrying with your pocket change, etc., etc..
Tim, got mine from either Adorama or B&H because I've not shopped for camera gear any
where else!
JDM's Extension tube set looks interesting! My photography gear budget could maybe do those!
