I've just ordered one. I'll follow up again once I get it, should be the end of December. In my research I found the exact same frame is used by a number of western resellers, retailing at 2-3 times the price.
So far, I've found Dengfu to be surprisingly communicative and pleasant to work with. They made some tweaks to the components for whatever reasons, upgraded the rear shock to a RS Deluxe.
With that all said, I'm not walking into this blind. I used paypal with an Amex card. I've not had a lot of fun in the past making claims through paypal but vendors are usually shit scared if you mention contacting them, they don't want to get shut down. Amex on the other hand will refund a claim in days with the right paperwork.
My biggest concern next is the shipping, I'm pretty sure the packaging is going to be sub-standard. I went with sea, it was another $150 for air and I'm not in a rush. This is the build out I went with
