My spill.. System X has a reputation for creating bad products. And I can say that they did not make the best, but neither did they make junk. Especially when you considered the prices at the time system X hit the market uncutting everyone else. From my experience in the early days the system X products were made very well. As they became more popular they cut corners and what not running their name in the ground. Hate them or not, they made a great impact on the cocker world... Not sure if it was good or bad, lol...
