Definitely get the uni bit. I got a set of them off of ebay and paid too much. Went into Harbor Freight the next week and they had a package of two - one for smaller sizes and one for the larger size holes, for about a third of what I paid. Work just as well.
I've got a SJP and a lid vent sitting in the garage waiting for me to install. Supposed to rain tomorrow so it sounds like a project!
