makeababy.ca has just come out with them. I've bought from them before...they have tons of stuff and luckily for me, it's local, so shipping is quick.
I just noticed their 10mIU/ml test and am thinking about getting some for fun.
I haven't bought these specifically - but I did test out my last m/c with Dollarama tests and was still getting faint positives when my levels were around 15.....

I've used the pink wonfo ones from Amazon.com and based on my tests after my m/cs they go down to about 10mIU/mL. I'd say get some and have fun... but know that you might be more likely to get a "falsa" positive (I had a few last cycle, probably a CP but with less sensitive tests I never would have gotten my hopes up).
