Bang-for-your-buck would be the India. It is about $25 from the big river and does a great job. I like it a lot. Plus it has a coarse side if you have some major repairs to do.
But the Arctic Fox is hands-down my favorite all-around stone. It cuts faster than the fine india and leaves a much cleaner, finer finish. It isn't pre-soaked in oil, so it works well with water, and barely wears at all. Hundreds of blades have been sharpened on it, and I've only flattened it once or twice at most. It really is the "if I could only have one stone" stone. It and any improvised strop will make an edge good enough for anything but your whiskers. Additional perks: it's American made and designed/sold by a small business and fellow forum member. But it is more than twice as much as the India, and shipping pushes it up a good bit further.
So, on a budget? Get the India and you'll be happy. It's good.
Don't mind spending on sharpening stones? Get the Fox. Grab an American Mutt while you're there and paying for shipping rocks. It's an excellent coarse stone.
Edit to add: it looks like the $25 is for the 6" India. The 8" which I have is around $30.Thanks for the feedback. I like india stones, use a medium and a hard arkansas and like that combo. Was considering something in-between.
