I've used one of these (can't remember what it was called or where it was from
My personal view is that it isn't any faster or easier to use. It does depend
on what you are used to though. When I was reading autorads, I used a program
on a PC called Seqaid, which lets you use 0,1,2,3 on the PCs keypad as A,C,G,T.
With a bit of practice you can type away with one hand (without having to look
at the screen) and use the other hand to help read the autorad.
The program also allowed you to type in the sequence twice and then compares the
two reads allowing you to change anything which doesn't agree.
This was the fastest way I ever found to read sequence gels.
(although now I use a Li-Cor sequencer which you can just leave to read the
sequence by itself).
Hope this helps,
