SKU 9682697. Pretty sure the chasis is plastic (it's really light), but the 510 is solid. Don't think you can mess around with temp curves and stuff like that, maybe that's a deal-killer for you.
Only had this a few months, so no idea about durability and longevity, but my experience with the various Picos I've owned has been very good. I have another of these on the way.
It's no worth it.
