At what price range would you say the manufacturing/quality defects start to vanish? I'm hoping not to spend into the ProVari range because I am sure my girlfriend will want a nice new mod if all goes as expected.
I'm sorry, but no I have no idea. I got tired of buying junk and throwing it away, so I bit the bullet and went Provari. The Chinese stuff is such a crap shoot, one might be great, the next junk, there's just no way to know!
If you feel like you have the knowledge and willingness to learn, the Chinese mechanical clones are getting good, I have a Nemesis clone that I just love! Good mods on the cheap, then throw in a Kick to get the VW you are after on the cheap? It's not as easy to adjust as pushing a button, but it still gives you all the safety factors you get in most VV/VW mods.
