I bought a set of Dark Energies on-line 4 or 5 years ago at Massmusic.net - and got very reasonable prices for them. I trust Paiste to be consistent enough that I can buy off the rack, and I was right. Didn't hear 'em until they showed up at the door. They work perfectly together. The Mark II 22'" ride is a thing of beauty. Use 17, 18, and 19 crashes with it, and 14 hats. Love that set.
Otherwise, I also love some of the Agop Istanbul and Bosphorus lines. I have a kind of random selection of Agops but wound up with a matched set of Bosphorus that I picked out from sound files at Cymbals Only
http://www.cymbalsonly.com/. Tony, the Cymbals Only guy, pulled 'em, set 'em up and played 'em to make sure they fit together. We were both surprised how well they all go together. Not a harsh tone or clash anywhere. It was the Traditional series in 14, 16, 17, 18, 22.
The Zildjian Ks are nice but I haven't liked the As in years. Prefer Sabian if comes to that. YMMV, of course.
