I've been using bhiner.com for most of my proxy buys to the US. Their website is pretty straightforward. You can search taobao on their site or copy/paste the taobao link into the text box. You put it in your cart and they check to make sure your item is in stock. Once it has been confirmed that the item is available to purchase, you then transfer funds via paypal to your "bhiner account" and they take money from there to pay for your stuff. I have proxied a couple of keysets and keyboards through them over the last couple of years with no legitimate complaints (had some OG cherry dyesubs held up in customs for 6 months...).
