5101 : Opinion/Advice...

Hi,

I have an option with an AD on a 5101 (although still looking for a 5004...impossible to find, it would appear.)

I like the look and feel of the 5101, but before I pull the (rather large) trigger can anyone please give some advice or opinion on useability (i.e. how delicate is the Tourbillion in real life?), and value for money (if there is such a thing on a $200k watch!!)...would love to hear from anyone - owners or not!

thanks

Tim
