I have a soft spot for Hammer and have just acquired a couple of Fu Manchu movies with Christopher Lee (ok they're not quite horror but close enough). There are a few sets of Hammer Horror stuff out there so you should have no problem converting to DVD. Some of my favourite Hammer movies include The Evil Of Frankenstein, Vampire Circus and Paranoiac (all available on DVD)
I'm also a fan of the Universal monster movies but I suppose that's fodder for another thread
