Don't know about 'best' but I love my 33rpm 200g vinyl! In theory the 45rpm version should be better. I couldn't afford an original issue LP, for which a mortgage is required.
I also have the current issue CD, which definitely sounds different (Mrs JWM pointed it out before I said anything), but I am quite happy listening to that as well. And it only cost me £2.99 with some other purchases from HMV, whereas the vinyl was a lot more expensive

At the time I bought it, you could only get it [new] from USA.
