Need opinions on this light?

so the pessimist in me didn't think that any of my seeds were going to germinate and I happened to go 8/8 :). Anyways, I'm going to be taking cuts as soon as I can, sexing them and dumping the doods, but I don't have a HPS yet. I came across this:

Sun System 2- 400w HPS - High Pressure Enclosed Ballast Mini System - Interior Gardens

and I was wondering if anyone had any opinions on them. I'm guessing they are going to run hot, but I'm not sure. A 400W is perfect for my space and I'm clueless when it comes to the differences between lights. Is a digital ballast a must?

Actually if anyone has a good recommendation for a 400W HPS, I would love to hear it. Thanks for the help guys, and a special thanks to StinkyAttic for helping me get my first seeds rooted (I followed her directions to a T). I wish I would have found this site sooner. I'm so tired of paying for bud. :hippy:

I don't like when they attach the ballast to the light assy. Just adds too much heat. Try looking at htgsupply on ebay.

sweet, thanks killer - I have a new leader. Hopefully I can get away with not having an air cooled hood for a few months. Eventually I'm going to upgrade my whole set-up when my roommate/best friend moves out, but that's over 8 months away.
