Jeff I have never had any problems with the Vovlo units nor the Mercs, $125 sounds real cheap, does it have all the brackets and related parts? The price you qoute for the Merc I am pretty sure includes everything you would need for a change over IE: complete system. Tank size and tube count may be the deciding factor, bigger and more tubes is better. I have an off brand three pass that is built like a tank 4-1/2 lbs heavier than the Merc four pass that I also have, both are SB units same size and tube count both are the resivoir type.
