Anyone use hydrofarm ballast?

http://www.hydroponics.net/c/522 1kw with wing relector $170.89

http://www.hydroponics.net/c/460 1kw with a more roundish reflector 178.19

my question is any of you ever use one of them?
they seem pretty good to start out with they are 120v/240v magnetic ballast i do believe

i was actually thinking of starting out with the one 600w for my 6 plants move up to 2x 600w for 8 plants once its all set and going?

if you do use or have used plz say and what if not any problems you have had with them before i buy either 1k or 1x600w

I've used the Xtrasun, SG Lite, and SG. They are all 120/240 and are solid workers. The Xtrasun has a 5 year warranty through hydrofarm as does the SG. The SG Lite has a 2 year I believe. All are pretty solid and may be worked on if needed.

there good ballast and a name brand....

alright so ill prob end up getting one of them... anyone ever used the website for ordering anything?

and for name brand or not name brand there pretty cheap from what i have seen so that was why i was asking if ppl have used and have or havnt had problems with them cheap usually do come with problems but sometimes not

another thought what you guys think 1x 1k for 6-8 plants or 2x 600w 1 for 6 plants at first then another later for 2x 600 for 8 plants in a scrog both ways either 1k or 2x 600w
