I have a 2003 Firefly on the way via a trade. I'll post my reaction upon receipt.
An update. The Firefly arrived on Monday. It was recently set up really well and was upgraded with an Allen Tailpiece and a bone nut. The bridge fit is really good too-looks like the stock bridge. Tone is pretty darn good. I have 3 mandolins and each has a different tone. I am really not sure which is "better" so hard to go there. For an eight year old mando it is in superb condition. Its a fun one to play.
