Love mars hydro as for the value and price I dont think there is better, but for 450 I would rather have someone else test them and review them before I even think about buying them, considering they have other similiar watt lights for cheaper, I would love for a tester to see what makes them better than the others. Let's say there old mars 100x3 produced 1 gpw and there new sun series 100x3 produced 1.5 gpw, I would just stick to the old mars as the .5 gpw doesn't make me want to dish out the extra money. That's just me. Like everything that comes out new, i wait for others to try and then buy, I.e so many first generation products having bugs and such
