Regarding these high prices...here's my thought...
If someone has $5,000 to spend on a PF, more power to them...it's their business....and to the seller, if the item was honestly described and with accurate photos and delivered as promised....then more power to them as well, a big congrats.
There will always be someone out there who lives with the motto that money is no object and they either want it for themselves or their children and dropping 2 to 5 grand on a Doom or Grey Hulk PF is as easy for them as me paying 0.99 cents for a 2 liter bottle of soda....
Oh...yeah...I failed to mention...i'm just jealous that i'm not one of them...
