I might not have seen it but if the vendors could make a package deal, I would think that they would make some easy and big sales...
Like:
a) Fuel box + ETG gauge...
b) Fuel box + ETG + pillar (maybe SRT-10)
c) Fuel box + ETG + Drop in filter
d) Fuel box + ETG + BHAF...
E) Fuel Box + ETG + BHAF + muffler
ETC... ETC... make the kits slightly cheaper then individual pieces and go from starters to out right radical...
Sorry off the subject... if you got a great deal on the Edge box, then by a ETG... if you decide to upgrade to a "all-in-one" box then sell the EZ and the EGT as a package and I bet you will get a good response for interested parties... . with that purchase price you will be $$ a head no matter what...
