IMO - Definitely worth getting are:
Underground Selection 11/92 - The Association mix of Quincey Jones - Listen Up on here is excellent.
Remix Culture 143 - As well as that Grandstand remix on here, there's also a dead funky track by Route 66 called Return to the Rare Groove Republic.
Remix Culture 150 - triple pack this one which has the unbelievable Brothers In Rhythm remix of Bruce Hornsby's The Way It Is.
Remix Culture 177 - Probably my fave DMC release, top remix of Public Enemy's Bring The Noise and a remix by BBBC of White Lines (Don't Do It) which I think well beats even the original.
Some definitely worth considering if cheapish are:
Remix Culture 109/1 - decent BIR remix of Clivilles & Cole's - Pride (In The Name Of Love) and a cracking Phil Kelsey remix of Blue Pearl - Can You Feel The Passion - be warned this is quite hard though.
August 91 Two - Nice Sasha remix of Third World - Now That We Found Love.
Underground Selection 9/92 - There's a Dave Clark remix of The Passions 1981 track 'I'm In Love With German Film Star' on here which I thinks nothing short of brilliant but I don't know whether this would be everbody's cup of tea as it's a tad hard.
Remix Culture 2/93 - Top remix of The Cult's She Sells Santuary done by Phil Kelsey which suprisingly enough is very, very similar to Papua New Guinea by FSOL.
Remix Culture 159 - 2 great remixes by Jimmy Gomez on here, one of Dilemma - In Spirit, the other of Donna Summer - State Of Indepedance.
Also an absolute essential DMC release is a best of triple pack called House Nation Classics which amongst others has got the BIR remix of Eurhythmics - Here Comes The Rain, the Delorme remix of River Ocean - Love & Happiness and the Sasha remix of Jimi Polo - Better Days (although VA I suspect you've got that remix already on DMC 106 along with Expose).
Phew that reply took a while
