considering a AP... Opinions for those experienced

[Canook]

OK ive come across a AP ROO Volcano 2010....
Now ive been on the look for a AP for a while and the volcano is def not my first choice i have found one for what i think to be a good price ($8500usd)

Ive got 3 rolexs,omega and a panerai so i want to step it up... my concern is what is the resale on them if i choose that its not for me? and is there anything that i should look out for specifically?

I can see what guys are asking for them on Chrono 24 but i take alot of that with a grain of salt, like anything what people ask and what they get are usually two different things and just because thats what they are asking doesnt mean they are worth it.

I have bought watches previously and paid a premium and then decided that im over it and lost a bucket load of money because the market has fallen out on them(Breitling ,Uboat,Oris etc...)

Opinions??
