Man, those bring back memories. I had some of the very first ones in the US when they came out, had a rack of over 100 of them making $300/day. $225/ea they cost then lol Volt modded them to be able to run at 400khash with some info that a member on here posted. Took me forever to disassemble them one by one and bridge a couple contact points, then reassemble. I think LTC diff was 9k or so and price was in the $30s, IIRC.
I'll see if I can find a pic of my rack...
Please do post the pics, that would be awesome to see. They were so badass when they first came out. Did you sell them all in the end?
YBcoin seems to be another good one for scrypt mining right now. Chinese based coin, volume is decent.
That whole rack only consumed like 1200W haha
Later I switched to using Rpis with Minera to control them.
