Hey @Skot, have a look; GekkoScience just released a BM1397-based pod miner!
https://bitcointalk.org/index.php?topic=5423227.0

I'm trying to get my hands on one as soon as they're available to buy. I'd like to mine a bit on it, but would probably also be able to get some serial traces off it for our open-source project.
I'd much rather buy this than an old, used S17 which may even arrive broken.

Wow, that's a sweet looking machine! I'd love to try one out too. I wonder how much they'll go for.

When comparing 'pod miners', right now there are 2 options; Futurebit Apollo and R909.
The Futurebit Apollo with 2-3TH/s costs around 700 bucks incl. VAT, while the R606 from GekkoScience (R909 predecessor) cost only 400 (incl. VAT). But the 909 will also 'only' put out 1.5-2TH/s. So 400-ish would give you a similar hash/ value, although at much higher efficiency. Roughly 100W instead of ~200W+ (should be much quieter, too, because of this). So therefore it might be sold for a bit more than the R606.
I'm wondering what amount of chips it has; should be just 4-6 chips, probably on the higher side, though, as they need some pretty fine tuning to achieve 500GH/s on Compac F sticks.

I'm also excited to see these changes to cgminer by kano. We will have to look into individual chip tuning as well, once the single-chip device works and we try out the first multi-chip boards.

[Kano] has been working on adding tuning features which include setting individual chip frequencies. Core voltage is adjustable in the range of 1.4V-1.6V per chip.
