I just bought last night a SS 510, with a power table, jigsaw and bandsaw.:D
Would like to upgrade it to 1. tilt on both sides, 2. a 520.
I have found on the net upgrades info but some mention the 520 and other the 520 PRO. Is there a difference between the 2 SS?
If yes, what other kit do I need to ...
