Unfortunately even though I 'bought' a CHIP some 6 months ago I have yet to actually receive it. It's very easy to source a BBB. Hopefully in the future thy become more available. Though I fear that will come with an increase in price.
I think their fulfillment process has been hit-or-miss. I ordered a CHIP in December 2015, received it in January 2016. However, my VGA adapter didn't arrive until late June. Part of the problem is their confusing order process; peripherals like the VGA adapter were being advertised as shipping in February/March, which was when I expected mine, but when I inquired about it via email I was told they had not even started physically building them yet, and I'd get mine "some time this year".
Still, for $20 total outlay I have something that is between the Raspberry Pi B+ and 2 in performance, with arguably better expansion (if you value GPIO over USB), and a few nice extras like a power/reset button and built in support for LiPo batteries. The downside is that it's based on an Allwinner chip, and that company is known for being open-source hostile. Supposedly they are trying to improve, but it does limit the range of operating systems available for the device.
I've experienced some serious fulfillment delays from them as well. Thanks for the reminder to get back in touch with them to see what's the hold up this time.
