Planning on doing a valve adjustment but looking to get a tool to do it on the cheap

Seems like an offset crescent wrench from Sears or the like would work just fine. Anyone use something like this?

Also thought about using socket attachment crow feet with a socket extenstion. They look like this and you can get them cheap from Harbor Freight



Input?
