You want the same i did one year ago when i started, one stone only, i read this forum through and bought a coti/bbw combo (and slurry stone) and learned how to use it with great results. I figured i'm set for life and i very well could be. But one year later here i am buying more hones, i loved honing so much i couldn't settle with that little, hard to use experience...So my advise go ahead get the one stone hone use it to it's fullness and fall in love with your hone but i'm warning you you wont be able to stop there.
