Prices for the UK GI Joes are high and steadily increasing. Here is what I paid for some of mine (keep in mind that I also think I got pretty good deals on most of it):
Red Laser: $50
Gaucho: $75
Blades: $30
Tiger Force Tunnel Rat $100 MOC
Tiger Force Blizzard $85
Stalker $35
Hunter $45
Red Jackal $40
Quarrel $25
Steeler $30
I got Jammer (MIB), TF Outback (MOC), the exclusive Mutt (MOC) and Spirit, and TF Psyche Out (MOC) in a large trade so I don't remember what value was on them. I want to say it was about $75 each on the carded stuff and $50 on the Spirit since he was loose.
I still need Dolphin and Moondancer, as well as the other two Tiger Force guys (Hit & Run and Sneak Peek) and I honestly expect to spend at least $400 acquiring them.
Unless someone can hook a brother up, that is......
