Hey you punk!
Yes, not being a dick is hard but you don't want to antagonize them (customer service is a bitch!!). You are playing it smart, bro', by keeping your cool...I have no problems so far with the digital ballasts..the thing that sold me is that they are light weight, wayyyy cooler than a magnetic ballast, and quieter,too. I think like you said that ordering online is a crapshoot...because the ballasts and bulbs are very sensitive and seem easy to damage (I think that goes for any brands out there, if you have them shipped, the longer the trip the greater the risk for damage.).
When I got my ballast on ebay, I held my breath when I opened it up, as I thought I heard that typical "this shit is broken" sound, but luck was with me and both bulbs and ballast were perfect. Ordering is like rollin' the dice!! I did get a bad bulb from them, and when I had to send the bulb back, it seemed very obvious that it was a grow bulb (on the claim form for UPS I had to write the worth of the item, and the packaging said "Fragile" on it, so any moron can figure out that $80.00 is an expensive non-household bulb.). I am glad I treat all delivery people very nicely, but I hate waving any RED FLAGS!
Props to you for keepin' your head on...I know after the last ballast, I would've snapped and just made it worse. potluvr
