Hes been out of prison for a while (unless he went back in since 2011 for something else?) but AFAIK hes not reentered the Sax world, or if he has he is not fronting the operation!
I dont know why his dodgy sax scam would influence anyones decision to buy a fine playing horn with his name on it, but I guess there are similar (but IMO not the same) ethical issues with WW2 era horns with swastika engravings.
Independent of all that I'm a bit concerned that the horn mentioned above is described as 10 or 11 years old, which would place it as made around 2008/9, several years AFTER B&S were out of the sax making business, so if true this is either an Amati or far eastern "wwbw" Guardalla, which while fine enough horns, are generally not considered to be the same top drawer horn as the "made in germany" ones. If its stamped MADE IN GERMANY under the thumb rest, then its almost certainly on original horn, but older than thought.
The B&S 2001 and all its bretheren were widely reported to be based on MkVI dimensions, but then again, what recent horn hasnt been

Many people have expressed the opinion that these B&S horns share the same sonic ground as Selmer, but the VI is pretty inconsistent from era to era and even horn to horn so Im not entirely sure what that means. I do know I like my B&S horns though, solidly made, reliable, great tone,. decent intonation. Massive bang for the buck at current prices.
