I haven't grown yet, but like you, you I was going to buy a ready made package. What I found is that it was a lot cheaper to make a list of what you need, and then shop around. I just spent under $1,100 so far (including shipping), and got 2 4x4 tents, canlite filter, 2 fan speed controllers, insulated ducting, 530cfm duct fan, 1000w ballast light kit/package, and a 600w ballast light kit/package all for less than what you're about to spend for before shipping for that package.... Lucky the people on this forum stopped me before I made that mistake. Plus with buying to light packages, I got 2 hps and 2 mh light bulbs...
It's your money though. I could get everything in that package for under 1k... Probably even around $800-$900.... You can get quality stuff without paying for the brand name too you know.
One more thing, I got a good price and free shipping on most of my items... I bet they'll going to charge you almost an extra $150-200 for that package... Looks more like a ripe off than a convenience.
