Yeah, Jamie, you are right. Gantaliano is thinking about EBBs, which TM also made for a time.
AEPs are leaps and bounds above EBBs. Cool stuff but sound real wonky and don't blow back. I agree about your comments on GBB reliability as well...GBBs are finicky and tough to operate with any sort of consistancy for any length of time, which is why I don't really own any.
