Haron Multi Sharpening tool

Hi there,

I need to sharpen some of my chisels, and don't have any sharpening equipment. I was considering getting this:

Has anyone ever used it? Is it a gimmick, and should i just buy an 800 and 1600 Wetstone instead?



Any other advice on a basic chisel sharpening setup that doesn't break the bank appreciated :)
