If you look at Anandtech's PSU reviews, the Earthwatts 430W has the same Seasonic OEM design as the Corsair 400W, except that the Corsair uses a quieter 120mm fan vs. the Earthwatts' 80mm fan. The Corsair is actually more conservatively rated than the Earthwatts. And Newegg has had it for $30AR or less a few times this year (currently $50AR shipped).
hifi - You've had a different Antec RMA experience than what others and I have experienced. I RMAed a SmartPower PSU and they promptly sent back a new Earthwatts.
It's too bad the rebate company Antec used went bankrupt and now Antec is rebate-shy. I've purchased a bunch of Antec Earthwatts, Truepower Trio, and NeoHE PSUs, all for no more than $9.99AR. It doesn't seem like Antec will be jumping back into the rebate game anytime soon though.
