[Skunkworks] USB OTG

I'm looking for a good USB OTG(On The Go) for my nexus 7. I understand the one for galaxy note works well with nexus 7 tablet. I havent been lucky to find a readily available one, a vendor told me they only ship and it takes10 to 15 days. Anyone who stocks or knows of a place where they are readily available? KR, Joseph.
