I have the 6x39 unit with the remote, Ive had it up for about two months, so far it seems to be of high quality. The only things I would reccomend changing are the stock bulbs, the 10ks are really yellow, and the actinics are very purple-ish. The remote feature is really cool, one cord for all three systems (2t5/4t5/moon). I would have liked it to be 3t5/3t5/moon, but thats not a big deal. I got mine on e-bay for signifficantly less than their website. It is a very good light for the money, but could use some improvements.
Hope that helps.
