Must-Have Monday

So simple, yet so genius! The "Opteka Hot Shoe Two Axis Double Bubble Spirit Level for Digital and Film Cameras" (thank you, Amazon, for your super long names). At any rate, this little baby will only you put you back $7.95. While I don't have my own yet, I can really see the value to this sweet thang!
If you're anything like me, being able to tell how straight your photo is is not an easy task. It takes time, dedication, and most of all...post-processing.
The big disadvantage I see to this (for me, anyways) is that it'll be a little hard to use my hot-shoe flash with this dealio on it. Anyone know any methods to remedy this without spending a fortune? Post!
