What happened to the "Full Metal Bracket"?

I'm this close (holding my fingers REALLY close together) to getting a pair of M2i's to throw in the rear of my room. I'll need something to mount them to my walls. I may even just say screw the credit card bills, and get the QS8's at the same time and finally finish off my 7.1 system!

Anyone here use the FMB? Are they any better than the $25 plastic jobbies I can pick up at Best Buy? Are they easy to use? Do I need to mount screws directly into a stud?

I live in an apartment and don't want to destroy my walls. I have zero experience with wall mounting anything more than a picture frame hook.
