Was excited until I saw the price. Too many other options for less.

Sorry Graupner, I love my both my chargers but after waiting two years on this, your late and it's too expensive.

KE Spins make me dizzy.
Looks like a great match to my GT1200.

Looks like a great unit but the price is way out of the ballpark for what it is.

Pulled The Trigger on Polaron 1500

I went ahead and got one. I paid $291 and change at Polaron USA by using one of their discount coupons (38300) . I figured this a little higher spec than a Hitec ePowerBox 50, for about $36 more (after you apply a discount to the Hitec as well). I made a quick video:

$300 strikes me as outrageous when you can get a more powerful setup out of a pair of server PSUs for <$50. If course buying brand new server PSUs retail would cost more than this, but there's a huge glut of perfectly good surplus ones that cost peanuts.
