* DISCLAIMER: I HAVE NO AFFILIATION OR EXPERIENCE WITH THE METALBONE KITS *

The Metalbone kits get a lot of respect at AK. (I keep mentioning AK because there are some solid Fisher gurus over there, from whose writings I am still learning.)

Your first eBay link appears to be from a guy who calls himself the "Fisher Doctor" or "Fisherdoc". From what I read, some people like his kits, others do not. Again, NO AFFILIATION OR PERSONAL EXPERIENCE with his kits.

Your second eBay link - I personally think that $185 for about $20-30 worth of parts is ridiculous. But then again, I prefer to do my research, see just what I need for replacement parts as well as parts for sensible modifications such as IBAM or IBBA, and then buy the parts from Mouser or Digi-Key. Sure, it takes longer to do the research, but I feel the end result justifies the time spent.

* Please note: I am not being critical in any way, so please do not read anything into the above. I'm just trying to help.
