I bought my a6000 via a Hong Kong company for £549 a few months back, and delivery took approx 8 days from time of ordering. For that price, I got the a6000 body, 16-50 kit lens, & 55-210 kit lens, so basically I got the 55-210 free compared to UK prices
I'd also suggest that if you get an a6000, look into getting a few spare batteries, of which I use a brand called ExPro which are at least as good as the Sony original, but only cost about £10 each. I also bought a dual charger (ExPro branded) as the a6k does not come with a charger, and being able to charge 2 batteries at the same time saves a lot of hassle. When using the a6k, unless you need to use WiFi etc., keep the camera in Airplane mode and you'll get at least 50% extra battery life.
Sony also updated the firmware to version 2.0 in the last few days, which added speed improvements, but also added a very welcome XAVC-S 50p/25p(PAL mode), 60p/30p/24p(NTSC mode) option for video.
With the improved video option as well, I highly recommend getting very fast SD cards too, I have a pair of 64GB Transcend Ultimate SDXC UHS3 cards which are rated for a minimum 60MB/sec write speed (actually write at 86MB/sec on my PC via USB3), and they are only £25 each.
There are plenty of cheap but excellent manual lenses to be used with the a6k as well, of which I have a few, and these are exceptionally good optics wise. To help with choosing old school glass,

As for low light ability, I find the a6000 pretty good overall, I actually keep it on auto ISO with a 100-6400 range most of the time, and it does the job well.
I switched from my bulky Canon DSLR kit to this, and haven't looked back, it's a superb camera for my needs, and my back is very grateful for the much lighter weight etc.
