the companies seem less reluctant to release them compared to the giallo type films. and a lot of the ones i have are DVD only imports which may now be deleted. Gambling City was on a label called NoShame and that is no longer available as far as i know.
I have heard that Rome Armed to the Teeth is supposed to be coming out on bluray in the US, so maybe from 88 Films as well.
ooh, and i will have to get The Climber. it is hopefully in the 5 for 30 deal at HMV
