Abbott - sorry I didn't get back to you. Think you made a pretty good choice - was going to recommend you purchase a new vise opposed to buying a used one (sometimes you are buying someone else's headache). Renzetti has been in the business for a long time. Lot's of good videos on youtube on how to use an inline spinning vise. Also keeps a good resale value....

"left handed" - on a Regal there is a set screw in front of the handle - loosen and flip the handle to the other side. Renzetti looks like you can flip the jaws around
