I recently bought a used Ryobi band saw, Model BS904G. With the exception of saw dust, it appeared to be like new. There was one small SNAFU though. The blade guide set screws were a bit reamed out from being over tightened, or the wrong tool was used. Neew screws were installed and all is good now. ACE Hardware has the screws and they are M4x6Mm. The set screws require a 2Mm hex wrench.
