For what it is worth...
I have a 2001 SuperCaliber, which is the model up from the Hoo Koo e Koo.
The Frame is fantastic; taught, with "Genesis" geometry so it's a nippy climber.
From memory, the SuperCaliber was mostly XTR, with RS SID SL forks. Hoo Koo e Koo slightly lower spec, (Manitou forks/LX Group?) but the frames are these are very, very good.
To be honest I'd reckon the frame alone is worth at least £100 if not more, but that's just my opinion!
