I am looking for a better bandsaw, (I have a shopsmith bandsaw shaped thing now). It seems like the standard saws that Woodcraft and Rockler sell are 14 inch. Looking around on Craigslist and other places I can find older 18 or 20 inch bandsaws for about the same price. I assume the more heavy duty solid construction of the bigger units would be beneficial. I think that I would also like to resaw hardwood logs into "free lumber" so the increased capacity would be nice.
Are there drawbacks to the bigger saws? I know I would have to cleanup, restore the older bandsaws.
