I think you missed my point on ease of repair..... I am not very mechanically inclined... Often when I take something apart and put it back together I have an extra piece or 2 left over... I like the fact I can completely take apart my Megalodon with nothing more than a dime for a tool and it will still work... BTW I have already screwed that up sort of..... And I don't think warranties cover toilet baths....I can understand where you are coming from and you want to be able to fix the prob yourself but on the flip side the VV mechanical box mods come with a 30-60 warranty where as the electronic VV ones come with a 1-2 year warranty. Many people like to have that piece of mind as they may not be as mechanically enclined as you.
