I want to get a wooden jack plane to rough dimension stock and thought about getting a Japanese plane. But after looking at some of the Japanese plane sellers' websites, I am more confused than ever. Way too many choices. So, can someone please share an easy way to identify which Japanese plane would best serve that function?

I realize cost is a factor and I'm not looking to buy a plane under $100, but I am not ready to spend $500 either.

Thanks in advance,

Steve
