Hey Shred, here's a good analogy for you about Chinese panels. You know Paul McCartney right? You know he's been playing his 61 Hofner bass since the Beatles dayz, right? He has never had a backup for that bass since his 62 Hofner got stolen. Why? Cause every Hofner violin bass he's played these last 40+ years sucks balls. They are nothing like his 61. They don't play right or sound right or whatever, and him and his bass tech know it and treat that bass like a Midwest sheriff does his beautiful blonde virgin daughter.
Chinese panels are like that IMO. The build quality varies so wildly that actually buying a panel that is "good" is like a one in a million shot. Chinese warranties are for the most part useless when you have to pay 80 to 100 dollars to ship it back to them. Or pay 30 bucks to ship a 10 dollar driver to you that you have to install. Chinese salesmen, for the most part, will tell you anything to sell you a panel. What are you gonna do if he lies to you. Call the BBB? Right a bad review here? Won't matter to him, he's got a world of people to sell to. Unless you know it's a great panel, made by a reputable manufacturer, stay away. Otherwise you've got to accept the consequences of your decision. Both good and bad.
For the money you want to spend and the size of your grow you can get a Vipar A100 for less then 300 off of Ebay, though you may need to supplement it. Or buy two. One now and one later. These are basically Chinese panels, but ones that are made according to Vipars specs by a company or companies that put out quality reliable products. 3 year warranty, though you may have to ship it to Canada to have it fixed, and they've just put out there latest models. Plus my dealings with their support has been great and they actually grow weed! This would be a much safer choice IMO than going with some company that makes panels that look like other panels. Total crapshoot if you ask me. You've got to remember the amount of factories in China is mind boggling. To find the company that makes company X's panels is like winning the Lotto. Probably never gonna happen.
And don't forget to check Area51 too. They might have a deal for you if you send them an email. Also there's DIY which could be perfect for you. Good Luck with your choices!
