Have a 4423 scope for sale. Don't remember when I bought it but now think its just like the 4425. It was bought from autonerdz and has two DVDs with it, one is John Thorton training with the picoscope. This scope comes from a one man shop so its like new. there's alot of the stuff that wasn't even used. 1500.00 takes it.
