If I were to pick 2 from the ones you listed, I'd go with the Skyline and Link. The Skyline is a nice, slim, light, manual flipper, and the Link is a bit more robust assisted one. The Skyline makes for an excellent slicer due to its thin hollow ground blade, and the almost sheepsfoot-like blade profile on the Link is pretty versatile. The Cryo and RAT II are both pretty nice as well. The Persistence and Tenacious just didn't fit me well (although if you through the Delica and Endura into the mix, I like those two a lot). I haven't tried the RJ Tactical.
As for an inexpensive sharpener, something like the Lansky Turn Box might be a cheaper alternative to the Sharpmaker for a somewhat-guided system. Something like a DMT Diafold may be more versatile, but it will have a bit more of a learning curve, since it's all free-hand.
