One our of under 17s regularly gets them froma cousin who works in their factory and they seem pretty nice bats to me - possibly a little overdried on occasion, especialy in the lower end models, and certainly the flattest faces I've seen, but nice willow fairly graded and well shaped. I don't know if the handles are great - there have been rumours that they're not super durable.
In terms of models, the Plus 5000 and above should be okay.
You're wrong about the sponsorship mind - there are quite a few Bangladeshis use them (Tamim Iqbal included) as well as Azhar Mahmood, a few Kiwis and a couple of West Indians.
