Since I first posted about Taobao, I have learned some more and I have tried a couple more agents. What I find is that there are many agents and they come and go swiftly. Some of it is fraud by the agents and some of it is fraud by the buyers, but it is an ever changing marketplace, much like ebay.
I have tired http://www.taobaonow.com/ and http://taobaofocus.com/ with good results. But, I have learned to be patient with them. First of all, we are in different time zones and I have learned to "do business" at around midnight to 2AM my time. It works much better. I still use http://www.go2tao.com/ or http://www.taobao-buying-agent.com/ for my searching, as I think overall, they get better search results. Then I go directly to the sellers item and link it into the other Taobao sites that I buy from. I can see that this is a kind of shopping that is not for many folks, but I want the lowest price I can get, for the same items being sold elsewhere.
My dream is that some day, some member from China will PM me and tell me that he will be the go between (like that's gonna happen), since even with some of the low prices on Taobao, the prices can still be haggled, but agents don't because they want their cut and less fro the sale amount, means less for them.
I still buy a few things from regular sellers like FastTech, or whoever might have something for sale, but with inflation, I just try to get things at the lowest price possible. As an example, I just ordered two different 50mm aspheric lenses and 30 of the 15 degree TIR optics. After Shipping, the lenses ended up being $5 each and the optics ended up being 66 Cents each. I was buying the lenses for $1.50 each before, so that was a big savings to me. The same lenses that were probably bought from the seller I used to use, since they came direct from an "optics company" this time.
To me, Taobao is still viable, but the culture, language and ethics differences are still hard and always will be. Patience is a must and it takes about 1 week, to 2 weeks to get through the order process, to the point of shipment, but I know that, so I order a month or two before I want the stuff (if I have the money).
There are other Taobao agents around and there are some I would like to try, but some do not use PayPal, due to all the fraud on both sides of the coin, so I don't deal with the ones that don't use PayPal.
