Yup, still have some for sale.
With regards to escrow, our preference is for someone to pick up locally in Vancouver Canada. We can demo the units in person as well.
A multitude of issues can happen with escrow, the escrow person may go missing or MIA for weeks, or mining gear is used then returned or claimed "broken". Because we have a no returns accepted policy it would be really hard to see how we could use escrow.
We have eBay and Localbitcoins profiles we can prove are ours with 100% feedback and hundreds of successful trades. Except eBay doesn't work for our return policy and LocalBitcoins is for Bitcoin trades.
If someone is serious, they can PM us and we can provide this information. We are also willing to self-identify who we are for serious buyers willing to self-identify as well and meet us in person.
