Film is not particularly hard to find, there are a number of good mail order suppliers and some shops including Jacobs carry 120 film, even, say it quietly, some branches of Jessops. Prices have not really changed a great deal, only increased slightly, whether this will remain the case is another matter.
Certainly the prices of the equipment have dropped dramatically, a friend has recently bought some Mamiya 645 gear, in good condition at a price that would have been inconceivable not very long ago. This equipment is of course robust, being built to withstand extended professional use.
