Sent you an email, not sure on cost. Always hard to guess or come up with a price, you would have a better idea than us of parts + time.
Would be good to get some of your money back or put it in to another product?
My plan would be to somehow fit my A500 in it, wishful thinking. Have seen a couple of hacks to get a USB keyboard working with the A500 so might be possible.
Anyway, maybe once you hear back from everyone that's emailed you, you could take an average price and go with that?
