Best Spy Comics?

Hey im looking for the best spy comics or something a bit like metal gear solid. Please only recommend stuff that won't be ridiculously expensive (really pissed off still about Books f Doom) also I live in UK so I buy it all from Amazon.

Winter Soldier was great during the Brubaker run.

I'd recommend Who is Jake Ellis? and Deadpool Pulp for some good spy-type stories.

Casanova and Sleeper.

I was wondering if Casanova was any good....

cool, anything more like metal gear(excluding giant robots) though?

also does anyoe know where i can buy books of doom for a decent price?

How could have I forgotten about Human Target? And Checkmate, Mind MGMT, Queen & Country, Secret Warriors and Ostrander's Suicide Squad. Also Global Frequency kind of fits too.

A good espionage-spy-type comic?

It's only a few issues in, but Secret Avengers has been really good.
