been looking at these for a while, paul rini of the good olde US of A makes what has been described as a premium EP at a extra low cost. apparently he uses ziess (is that the name) glass in the EP and fashions his own barrel etc...
they are pretty plain to look at but from what i have read work exceptionally well. @ less than $30US they seem too good...
anyone used one?
