Would you happen to have a link to the cheaper ones you're looking at?
Really anything that you're seeing brand new now is probably a new enough version that it will sound decent.
The 1994 UK remasters are said to sound very good and are even prefered by some here. Anything showing a release date after that from the UK is going to be from those masters, I believe. They just get re-issued occasionally.
The 1991 Hollywood Records editions from the US are very nice for the most part. There are a couple of them which don't sound too great.. 'The Game' is a bad one in my opinion and I can't remember the other at the moment, lol. But some of those do have nice bonus tracks (not the remixes, but b-sides and 12" mixes)
The really expensive ones you might find, from 2001 and 2004 in Japan are also mostly good and the 2004 editions are in card sleeves/paper jackets reproducing the original LP art beautifully.
Avoid anything from 1998. There are some Japan/UK/U.S. "remasters" which were released in card sleeves also, which were abandoned after the first 8 albums because they sounded shitty. Too much noise reduction made them dull.
