I've had my 8500 since '03. I has saved me countless times and is definitely money well spent! Unfortunately I've been getting many Service Required messages lately and I believe it's time to retire it. So I've been researching replacements and ended up here.
I'm pretty much sold on the V1 b/c of the arrows, but will continue my research. Fortunately a co-worker has an older V1 that he let me borrow to test out. I'm going to put it side-by-side with my 8500 and see how they compare. Should be fun!
