As an fyi, after 4 months, the LC100 is finally back in stock with the Florida eBay seller:
Universal-Joint-Febest-AST-LC100
I had ordered an LC90 back in September; but the LC100's were sold out. There were only some available from international sellers for stupid money.
Just two days ago I received notification on the eBay watch I'd set back then and I ordered one. For a mere $11, consider getting one while they last.
