I presently own a Delta 6 inch professional jointer model 37-195. I ran across a brand new (still in the box) DJ-20 for a great price (less than $800) although it is 2 years old. My question is--What does the 8 incher give me for the extra money other than the ability to joint a wider board? I know the table is much longer, but I am not sure what other benefits there are. I would probably sell my 6 inch if I buy the DJ20. The DJ20 also takes up a lot more shop space. Is it really that much better?
