I have, currently my Schecter E-1 FR S is blocked with a small piece of wood that's cut down to fit, and I think $1.25 in quarters wrapped in just enough electrical tape to fit in the front of the block to prevent it from raising. It's worked well for a while now. I set it up for E standard and it didn't have any issues going to Drop C, I didn't go into Drop B much at the time because the string tension was a little less than what I liked. But I'm sure it'd work too.
Seen plenty of people rave about the tremol-no like Radu said, I was looking at it for a while but decided not to as the wood block/coins worked well haha.
