Had to sell my first S6 a couple years back to pay bills. I've said to friends how I wouldn't sell certain guns. Selling that S6 literally put me into a depression. But then I bought another one and replicated my setup. Now I'm happy.
They truly are exceptionally fine examples of pnumatic marking equipment. Loads of fun to use and when they're setup properly, zero maintenance. Hoping to bust mine out a bit more this year.
