I have bought and used many of the torches sold by the big Chinese sites (focalprice, DX, Dino, kaidomain, Manafont, bestofferbuy etc.) and eBay with no major problems. All my torches are users of some sort.
Usually you can find online coupons for 5-10% off for them.
However, you need to be specific about which torch you are interested in, as some are better than others. Also some require Li-Ion batteries to get the most out of them.
Have a look at a relevant thread I started in reviews in which I talk about some of them.
Also look at Budgetlighforums for a lot more details on many more of them.
