I recently purchased a "Sigma Picador" off Ebay for 82$ (it had the newer Sigma logo on the headstock) and received it today. I just took off the inside picador sticker to discover it is a DM 19 MIJ Sigma - late 70's/early 80's model - solid top. Great condition for its age, some fret wear and a few bumps but sounds and still plays great!!
