I've been looking on Alibaba for months also. It seems that unless you live in china, or are an expert at due diligence, your extremely likely to get scammed. Even so, China is the place to end up as its the best for price.
I've found 4 suppliers, both in this country and america. Gonna start with this country and when i've educated myself on importing i'll move to yankee land.
The products I'm looking at are xbox stuff, sony sp stuff, ipods, mp3 mp4, mobile phones and accessories, hand held games machines etc.
I will be offering a dropship service, and I wont be charging for it.
Watch these boards, give me a month and i'll hopefully be ready. initially it'll be mobile phones, then i'll branch out.
