The LemmonRx recently caught my eye and I found this thread to be quite interesting. The thread gets better from the second page on after a rep from the LemonRx starts posting.
It seems the Lemon, despite the name, performs quite well and the price is amazingly cheap. The shipping to the US is a little over $3 per order and arrives in a couple of weeks. I can't seem to find any downside.
