I have been looking for a marvel band saw for quite some time and am curious if anyone here has any knowledge on them? I have only used a relatively new machine, but there's no way my budget is going to allow for it so I am looking into some of the older models. Thinking of buying and refurbishing? parts/interchangeability?better models than others?any info or leads on where to buy????Thanks in advance for any help. also I am located in california
