I've got two basic types of handles that I use for leather floggers- lighter with wire wrapping only for balance, covered with silicone tape, and heavier ones with wire wrapped the full length of the handle and for balance, with silicone tape over it. On these I can put several different types, weights, lengths, etc. of leather:

These are what I do the most of- pricing will vary depending on exactly what you want. The lightest warmup floggers I'm selling for about $65, the medium-heavy suede for about $120, heavier stuff I'm charging more in the neighborhood of $150 and up. I like doing matched pairs because that's what I prefer to use myself, I offer a small discount in those instances.
