I order from them, as a matter of fact I have an order on its way right now, but I never order from their EBay sight, go to www.htgsupply.com
and click on products. The prices are a little more spendy at their store, but I still prefer the higher prices over the EBay risks.
The 400w HPS with everything on their sight is about $200, I don't know if I would get it. What I did was to pick up a 400w ballast with socket and power cord for $44, and the AGrowMax Altra blue bulb for $59, I already have an extra hood, I also, picked up a 1000w HPS for $105 from them, the shipping was $90, but I live out side of the Lower 48 states, so shipping is a little more here.
All the stuff is new, and not refurbished and comes with a 2 year warranty. Hope this helps some. By the Way they are a real store, not just some online EBay sellers, they have a real store front in PA.
