No names off the top of my head, but a good third party sourcing agency can actually save you a bundle as well, not just in cash, but in hassles.
A lot of these companies already have good established working relationships with factories, so can quite often not just take you to what you need, but can also get you a better price than what you can get on your own.
Things like language barriers vanish, and business can be a lot smoother.
Still have to research the third party, plenty out there are just fronts for specific factories. They won't get you the best price, they will just point your order to their own manufacturing process.
This company sounds quite interesting, well worth looking at for anyone seriously looking at the Asian market, but as Wes has said.....wasting your time if you are not a big buyer!
