I got the one JP shows, ebay $40 delivered. works great, clamp it in the vice, and then just squeeze the valve springs, then you have both hands to pop out/in the little keepers. hey, if you think you will only use it once, you could sell it on ebay. I almost sold mine, glad I didnt, in the last 4 years, done about 10 engines!! (70cc to 250cc hondas)
