Get this for $25:
it's perfectly capable of taking care of a straight or few, for more razors for long term, you'll want a finisher like the naniwa 12k gouken which is only $60 on Amazon, but worry about that after you can get lapping films to give your razor a pleasant edge, honing takes learning.
You want a set, but unfortunately the price will get high quickly with that. You can get a 1k bevel setter for $65, a Norton 4k/8k for $120, then the naniwa 12k I mentioned. In 1k Shapton or Naniwa will work well. Then you can get a DMT lapping plate or atoma 325 grit for $50.
I see some new cheaper naniwa stones in the gouken variety at 10mm which you could grab for 1k, 3k, 5-8k if you want, I like the gouken 12k and many people find it a great finisher, but I've never heard of or seen the lower grit gouken stones, it stands to reason they're probably good like the 12k gouken is.
Another strategy is to just buy a single natural stone, a coticule, and learn to do dilucot where you change the grit from coarser to finer as you hone with developing slurry and thinning it over time. Can do everything with one stone like that, but it's an advanced technique you'd want to study in detail and would take more to learn (I've never done it)
Again, if you don't want to mail for sharpening, start with lapping films I suggest. Get a usable edge and shave. Honing is so secondary because you'll be struggling to know if issues you have are the razor or your technique when you learn since you don't want to get a shave ready razor from a honemeister
