A Two Evil Eyes 4K UHD arrived today (from diabolik dvd in the States). It's not officially released until almost two weeks from now so I'm quite impressed with the service. Also a French blu-ray of Hammer's Curse of the Werewolf is being delivered by Amazon today (the UK bd is useless since it crops the aspect ratio).
Other recent buys are the OOP Blue Underground Dario Argento's Inferno on blu-ray and an Australian Top Secret blu-ray.
I've got a Koch Media Inferno bd already but wanted to see the BU version since it has a different colour scheme to Koch/Arrow (stronger blues and reds). The Koch is cinematographer approved but many feel Blue Underground is closer to theatrical exhibition.
The Australian Top Secret looks quite rough with video noise on display. But it does look noticeably better than a dvd and I could be waiting for years for another alternative blu-ray. I don't regret buying it, I had a blast watching it with my wife (hilarious film!).
