The spools themselves sell for $30-50. If you get the kit, which is just the spool plus the little leader piece that goes on the base, you're usually looking at $100. I had the spool only and it loaded easier than the normal spool, I don't know how much having the piece that goes on the base would have helped. In the end I sold the spool (in fact, the one that Joe is talking about might be my old spool that I sold, I can't remember who bought it). I sold it because I never used the M2 where "speed" of any sort was a necessity, so it sat around.
