Daniel, that is interesting... I use only Berea and CSU kits.. I have never been impressed with the kits from PSI, I don't think their platings are up the other two suppliers, but that is just my opinion for what it is worth...
I have (other than stated above) never had a problem with a Berea kit or the platings on their kits.. I make a lot of Perfect Fits and Double Twist Euros, and just got a couple of El Grande Elites in Platinum from the guy going out of business for $5/ea. Had to at that price... LOL
I also agree that CSU makes a wonderful kit, that is why they and Berea are my primary kit suppliers.
As for the Atlas, I have to agree that it is a nicer kit than the Polaris... it has a better selection of platings and I think the mechanism is smoother. If you look at Bill B's instruction page, you will see how I convert one to a pencil using the Perfect Fit pencil mechanism... so you don't need to purchase a different kit to make a pen/pencil set... it is a little tricky, but not out of the range of anyone here who can follow directions.
