I imagine all of us enjoy testing/reviewing equipment. If the sole purpose of The Guinea Pig patch is to generate a couple bucks through purchase, then sure, good idea. But it doesn't seem like something that would differentiate one person from the next since pretty much all of us here would love to play with new things we haven't gotten our hands on in the past.
As far as an Innovator patch goes, I think The Tinkerer patch covers this or is close enough to be considered the same.
That's just my two cents. I am curious to see what others think.
