I only buy records super sporadically now, so my finger is not on the pulse.
As I said above Beatport is good. And I have also found some great tunes listening to
http://protonradio.com which can be superb.
Good compilations are most of the Global Underground series', Nick Warren, Hernan Cataneo, Bedrock compilations, Jimmy Van M, Pole Folder, Sander Kleinenburg, Danny Howells, Satoshi Tomiie, Luke Fair, Tom Middleton, Desyn Masiello, Jason Jollins, The WHOLE Northern Exposure Series and others.
I also like to include Sven Vath, Dave Clark, Richie Hawtin and a few more from the techno end of the scale as obviously prog isn't always "progressive house," but a mixture of proper prog, deep, minimal, tech, tribal tech, breaks and some of the more mild techno. There's also a fair portion of trance, although less from the acid and psy end of the scale and more the easy listening sort, but I think that sort of goes without saying.
Producers and labels of note would be many of those mentioned above, Sasha, obviously, Bedrock Records, Hope Recordings, Saw Recordings, Slacker, Guy Gerber, anything buy Van Bellen as he's godly, Automatic always did some good tunes, Hooj (sometimes ropey as hell), Steve Porter (some of his shit is fucking amazing, see
Amber - Anyway), Fade Records, Additive (some ropey tunes, but some classics, check this for
sexiness), heard alot of good stuff on Morrison Recordings (mp3 only I think) and others.
I could probably go on, but in all honesty I haven't actively kept abreast of what is great for ages, but tunes like those linked to above and, like most prog, are almost timeless.
Some classics for you. (in my opinion.)
