Chinese made TTL wireless triggers?

[ecphoto]

I was wondering who uses them on here and how well they work. I'm referring the the Pixel King ones and the Yongnuo 622C set of triggers. The PK ones are 75 each transceiver while the Yongnuo ones are 95 for two.
It would be nice to be able to my strobist work with out so much guessing, but I can't afford Pocket Wizards.

Any thoughts on these?

Thanks

TTL for studio work? Forget it. TTL is now what you are after. What you want is complete control of each strobe to be able to set the power from where you are standing. That is the feature you are looking for. This is what will happen if you use TTL:

1. You zoom in and out with your lens, your flash power changes.
2. You move your framing, the flash power changes
3. Your subject moves, the flash power changes
4. Your subject wears white, the flash power is lower
5. Your subject wears black, the flash power is high

You want manual man... The only time you want TTL is for an event coverage IMO.
