This Lisle hone is the only one I have any experience with. I expect Sunnen is much nicer but the Lisle seems to work OK. It's a lot of work to hone .002 and have to be careful to hold size for the length of the cylinder. I try to run the boring bar as close to size as possible to minimize honing.
I would rather buy a tool than pay someone else. I'm sure many members here feel the same way. I like to figure out how to do it myself. There are limits though. Pretty tough to justify a crankshaft grinder in my shop.
