I agree with @apvx - the Fasttech forums and review sections are an invaluable source of information on which items are good purchases and which may be duds.
There's nearly someone always willing to 'take one for the team' should a new item appear that hasn't garnered any reviews yet so that everyone can benefit from that experience.
The forums are something of an, errm - 'free-wheeling' place - far looser and more Wild West-like than the tightly-moderated forums here, for example. There are lots of good, knowledgeable people, to be sure, on the FT forums.
Quite often, clones turn out to be *better* than the originals upon which they are based - this happens when the clone manufacturer has a chance to listen to feedback from buyers of the original items, and makes changes to improve them.
The 'Orchid' range of RTAs (of which I am a *huge* fan to this day) is a classic example - I think the cloners are up to a v6/7 now, even when the original manufacturers only released two version of it AFAICR.
