I bought the reissues of the first 3. I haven't had time to really do a good comparison, but the seem to sound better than the 1994 remasters. To be honest, I thought the 1994 versions were terrible, so just about anything should sound better. Mothership is OK, but I have it on CD. Any time a recording goes through some type of digital process and is not 100% analog, to me it just sounds like better digital, so I won't get it on vinyl. Either way, though, Mothership is worth buying.
