I have decided to go pressurized and have tried to search the site to get an idea of what everyone else is using but it doesn't seem that a lot of people are pressurized. I saw several threads from back in August that seemed to suggest that several members were ready to make the plunge. So of those that have, which system did you get and are you happy with it (ease of installation, ease of use, does what you expected, etc.). With such a big investment (since I have 2 planted tanks and may end up getting a second one if I like the way the first works), I want to know I'm getting the best. I don't mind paying a little more as I am a firm believer in the old saying that you get what you pay for but I don't want to just buy the most expensive system thinking it is better.
