Well, I hear the Spyderco series of medium, fine, and ultrafine are a huge hit and an excellent value - you could also go Belgian blue and coticule? I have a coticule and love it as my finishing stone - and with a slurry it works somewhere in the 4000 to 6000 range (without slurry ~10,000). A Belgian blue is coarser than this of course, but also produces and excellent edge, from what I hear, and can be used with or without a slurry.

Just my $0.02...
