Shell sets don't seem to be sellingHLD 590 sold out immediately and only 100 were made (for a 150th Anniversary) 150th Anniversary Steel Kompressor Snares (in USA) are only available from 2 retailers and were released with no fanfare; while the catalog counterparts have had a price drop. No word on future released of other 150th models from the rest of the Kompressor Sonor continues its recent years tradition of offering no swag whatsoever (in USA)
