Ordered a Chuwi Hi10 in February, and been very happy with it over the past couple of months I've had it.
Got mine from gearbest:
http://www.gearbest.com/tablet-pcs/pp_244798.html and it took about 2-3 weeks to get to me from ordered (can't remember exactly) on free delivery. Didn't get hit for VAT on import, but obviously this is pot luck. Can't say whether the service is better or worse than other Chinese resellers, as have only used this one.
The screen is brilliant - 1920x1200 at 10 inches is always going to be sharp, but I can see some people finding icons, etc too small without using scaling in Windows and other apps, so you're reliant on how good the apps you'll be using are at handling high DPI settings. Touchscreen is reliable enough, and it came with a perfectly pre-fitted screen protector that's a fingerprint magnet, but I haven't taken it off yet so can't say if the screen underneath is better or not.
The tablet is very responsive and has done everything I've asked of it, provided you're realistic. You are not going to be running Crysis on it, and asking it to do supercomputer calculations will be stupid, but for basic internet, MS Office, and other "light/normal" usage it's perfect. I normally have one, two or three internet tabs open in Edge and it flies, but last night one of those was an ad-filled page and the whole tablet slowed down, Task Manager showed the tab was using over 2GB of RAM. Closed that tab and it went back to nice and fast. Even managed to run Heaven Benchmark at 1080p with Ultra quality and Extreme tesselation without crashing! Only 1 - 1.8 FPS, but it still ran with crashing or catching fire. Battery life seems pretty good to me too, with a few hours watching films on it of an evening barely making a dent into the battery (generally still 80% showing after a couple of films with the brightness on lowest). The tablet's also pretty light, certainly not noticeably different to the first gen Nexus 7 I was replacing, which is my only frame of reference outside Smartphones or laptops/desktops.
The cameras on the Chuwi Hi10 are rubbish, both front and back are suitable for Skype in good light only, forget anything else. The speakers are also pretty rubbish and not very loud even at 100%, but the headphone socket works fine so I just use headphones when watching Netflix, etc.
Connectivity is where the Chuwi really shines - it's got a full sized USB2 port, a full sized USB3 port, a mini HDMI port, microSD slot and a microUSB port that's used for charging or USBOTG. I've had issues getting high speed microSD cards being recognised (a SanDisk Ultra 64GB UHC1 card wouldn't work, but a regular 32GB Class 10 works perfectly). Not had a problem with the WiFi, and it's streamed and played some 4K videos fine from my NAS.
I've used it so far with an Anker USB3 to USB3 hub with Gigabit ethernet port, a microHDMI to full HDMI cable, a cheap eBay microHDMI to VGA adapter, a USB powered DVD writer, and any number of USB2/3 USB sticks and external 2.5" drives, and not had a problem with any of them - worked seamlessly.
I haven't tried any of the other suggestions in the thread, so can't say which is better or worse, but I'm quick to find faults with tech things and I've been very impressed and happy with my Chuwi. The front and back don't have the quality feel that, say, a recent iPad has, but for a cheap and light tablet it does feel pretty solid. I've certainly never felt the need to be cautious handling it in case I break it.
Overall, very, very happy with my £127 tablet and would recommend if the specs sound like they'll fit your purposes.
