I will agree that the initial setup can be costly, but I made the switch several months ago and couldn't be happier. I got tired of mixing the DIY solutions and the gas was never constant. I had algae problems all the time. It's so much easier IMO to just set the bubble rates and not worry about it. Depending on your tank size, you could easily go 4-6 months before a refill. Over the long term, if you add up all your costs & time, I think most will agree that going pressurized is the way to go.
