John, I have no experience with the SilverFast software but absolutely LOVE Vuescan for trannies, at least. I'm an experienced scanner but new to the SS4000 myself.
I've spent $40 on far less useful things. :) Hamrick software has a full featured demo you can d/l from www.hamrick.com that you can try. Paying for & registering the software will get rid of the diagonal lines the demo puts on the output. Good for a test drive before you buy.
