Yea, its not cheap but something for something, and nobody need to know how much you paid

of course, Im not saying that this it the best bov in the world but can be very useful, especialy in country like AU where VTA is illegal 
would love to know if it messes with tune changing it from venting to reciculating like that? steve?
