The Dial on the 6538 is a dead giveaway that its a rep. But if its your first foray into reps then its is a good price. I bought one ages ago but didnt like it so sold it and saved up to buy a more convincing one.
Very nice work.. I am just waiting on a crown tube from Yuki for my case. From what I can see here, the results will be great however I will be using an ETA2846.
