I have last years El Mariachi (17" frame) of which I am the original owner. It has been ridden quite a bit but is still in good shape, despite some scuffs and scratches in the powder coat.
Right now It is set up as a single speed, but I was planning on putting the stock 2X10 SRAM X9 drivetrain back on it which I took off after two months of riding. It has been sitting in a box since. I can also set it up 1X10 or have an unridden Shimano Deore 1X9 setup and can easily form a 2X9 package if that floats your boat.
I have some Gravity Step Up cranks which will acompany any single ring front configuration or some FSA three hole majiggers or Shimano XT's for dual ringing. I can put Avid elixers or an older Shimano Saint Front, XT Rear brake setup on it as well. I have enough parts to cater to pretty much any interest.
I guess a baseline price for YFF's with the SRAM 2X10 setup with the Avids would be $900 and things change from there depending on what you want.
