wicked!
still can't afford one though 
want to bring the price down more? 
We really hope the price could go down to more affordable range like $20~30, but the module contributes 2/3 of the total cost, which is not
decided by us.

Yes, I don't think your board is badly priced. I have seen the sparkfun one and it makes yours seem very reasonable. If I ever need one then yours will be the one I'll be looking at.
I think if you could get to $20-30 then everyone would be picking them up as they would be a steal at that price!
