Identifying a lure as "expensive" is dependent on the purchaser. Some of these lures are considered expensive while others are not. I would consider the RAGE tail products very expensive when comparing to other plastics, but cheap when comparing to overall lure pricing. If it catches fish though, i don't care how expensive they are, and the RAGE tail product line generally catches fish.
Following RW's format and adding a little.
Topwater: Yellow Magic popper, Rebel Pop-R with a shaved lower lip
Jerkbait: Rapala X-Rap (still learning this one)
Shallow crankbait: LC (RC) 1.5, 2.5, Rapala Shallow Shad Rap, Rapala DTFAT1 and DTFAT3, Bomber Model B(a personal favorite)
Lipless: though not as expensive as others, the Red Eye Shad has done well and the original Rat-l-trap.
Deeper: DT10. I don't generally get a chance to fish water deeper than 8-10 feet so I can't comment on anything deeper, but I have caught my fair share of fish off of the DT10
Plastics: Rage Tail, ZOOM, Berkley (Order Not Important)
Jigs: NorthStar Pro Series, KaRu Poison Tail and Football, Omega Pro Structure. Though they aren't as expensive, Backwater jigs have done good as well.
Spinnerbaits: Northstar Custom Tackle, H20 Express
Buzzbaits: never caught a fish on a buzzbait
Frog: ZOOM Horny Toad, SPRO Bronzeye
Hooks: Owner, Gamakatsu, Mustad, VMC for Trebles
Line: Power Pro - 30lb for bait casters and 15 for spinning (green)
Trilene Big Game 12 lb mono (Green)
Reels: Shimano Curado 200E7 for lighter lures and Abu Ambass. for jigging and worming.
Rods: I have had great luck with Falcon brand rods and Castaway brand rods.
