Most people realise from experience that a 45 reissue made from a sub-standard digital transfer will be a pale imitation of the real thing. So vinyl collectors will opt for original 45s. If anyone cares enough to want vinyl at all, they usually want the best vinyl. Plenty of great (more common) original 60s garage 45s are available for low prices, sometimes for less than a reissue. For the rare stuff, it's nearly all out on LP and CD compilations, or download.
