Automated water changes... I think I'm going to give it a go!

I'm looking at setting up automated water changes using a liter meter III system. Does anyone have any experience with those systems or have any they want to sell? If I go with this system I will probably be buying new resin water tanks and selling my brutes. So let me know if you are interested in buying my trash cans :) I'll keep everyone posted and have you all out after I get things up and running.
