Sagers are made by Clevo in Taiwan. Clevo (ODM) makes barebones and sells throughout the world to smaller companies that brand the laptops with their own name. The biggest difference between the (Dells, HP's and Lenovos - OEMS) are that the OEMs design the laptops and the ODM's build them. Clevo designed their barebones and sell to the Boutique companies such as Sager and Eurocom and others throughout the world. The boutique brands add hard drives & memory based on what the buyer wants and add their own brand identification. Sager and Clevo typically offer advanced technologies in gaming before the big time OEM's use the new technology

Xotic lpc digital,(both of them deals with sager branded clevos), hidevolution has their own brand called EVOC, eurocom also has something similar, these are all the North American resellers of Clevo
Azom i believe are the Indian ones , there are countless others in different parts of the world
The best place to get more information about Clevo reseller is indeed NBR forums , you will be able to find owners of different models and Company reps ,very active there
What i have gathered from the Forums are , they are generally quite reliable, and quite easy to take apart( obviously cpu and gpu is soldered in but the rest of the parts can be changed relatively easily compared to other branded names )
The risk is same as for anything you order from US , no warranty if something happens , you might as well end up with a big brick (unless you can find someone to repair it , it will have warranty in US for a year off course) ,this can be avoided if you buy from HIDevolution ,who offer global warranty, but at a cost ( i think its $150 plus , which gives you option to ship free twice a year for repair , if needed , check their website )
Xotic is the cheapest option of the lot , they are also good , i have infact ordered the model you mentioned from them , im yet to recieve it , will get only by december first weekend, when my friend will bring it , currently it is with him and the model has started and working fine, yet to stress test it
My advice would indeed be to get from HIdevolution if you can afford , they have a very responsive company rep active on NBR forums,and he is there for everything , also you will get a modded bios called PREMA bios , which gives you a lot more options ,
the reason i went with xotic was, i had to cut corners somewhere and i decided to take a big risk, since i was way over my budget
Another option you can look at is the ALienware 15 r3 , which also has the same 1060 gtx 6gb , but with core i5 , and you can get it for like $1215 right now, after using a coupon on the dell website ,
and also hangaround different retailers, you never know whats gonna turn up during blackfriday and cyber monday
BTw here is a review if you are interested , this is the Gsync model, which is i believe sager 8152, 8151 has a TN panel
