I have the RBI 220VS which is the saw you are looking to buy. It is good and the price is fair. I too do not like the blade tensioning lever at the back it just seems a little hokey to leave the cam lever at different angles to get the desired tension.
Arthritis in my hands has diminished my strength so when inserting blades I have two different size Alan wrenches to do the job. Now, instead of having a hard time fastening the blade strongly enough I have to be careful not to over tighten. The manual for the saw is available on line.
I bought mine used and the table has been a little chewed up by the blade and replacement tables are no longer available. I like Flying Dutchman blades.
