There is no doubt that the Chosera 1k is the best bevel setter but in the OP you had specified 'economical.' An ideal setup to my mind would be the Cho 1k, single grit Norton 4k & 8k, the Naniwa 12k, and either a DMT D8C for economy, or if you want to go whole hog, an Atoma 1200 diamond plate. The single grit Nortons are 1" thick, can be turned on their side for honing warped or weird grinds, and you don't have to soak the 8k. More $ for the initial investment but you'll never wear them out.
