I would second the recommend for checking out Paiste Signature Dry Ride or Signature Dry Heavy Ride. Both are very musical with the unmistakable pingy, bright clarity for which Paiste is known. The Zildjian Earth Ride is also a good suggestion, which someone else mentioned--that is a very clear, pingy ride with very little wash.
It all depends on what style of music you play, too. I wouldn't recommend the Earth Ride or Paiste Signatures for jazz. These kinds of rides are great for rock or fusion, where you want that "ping" to cut through and be heard (think Stewart Copeland ride sound).
For jazz pingy ride sound, the Sabian AA Raw rides are pretty cool--dark with some wash, but still quite articulate.
Overall, for a clear ping note, you cannot go wrong with a heavy weight Paiste Signature or Paiste Dark Energy ride. Paistes have great cutting clarity to them.
