I think for one-offs and truly rare limited dist, drawings are good.
For pedals that are going to be made for a while, I would favor a list. At least that way you know you'll have a chance to buy at some point, rather than trying to rely on blind luck.
In any case, it'd be nice to have some sort of filter (a fair one) as to who could win a drawing. It is good to see new faces on the forum, but if a guy with 1 or two posts won the right to buy a pedal, that would seem kind of unfair in light of the rest of us die-hards.
I know that sounds selfish and it is, but as the saying goes....just sayin'!
Also, for someone who wasn't opposed to being shady, what would stop a person from creating multiple user names using different emails and entering the same drawing multiple times?
