Zandor knows his stuff.....If you just watch the boards and do searches just about every question you could ask has been asked and answered here before. Best advice is to read read read....and make sure you pick up a grow book....just so you can keep reading even when your not online!! lol
Best of luck and the 1000 is a great choice...I have a 430 and I am trying to upgrade to a 1000 now.
