James, no problem. You're right that the both iS133 and iS122 seemed to be possible candidates mentioned by the original poster, and between these two the iS133 would be more suited. I guess my suggestion targeting the iS144 was predicated more on what the optimum board would be for such a heavy guy.
Given the bottom line choices mentioned in post #15, it seems to be more of an apples and oranges thing with very little room to move. Frankly, when considering an important investment like this, I like to go for the optimum, even if that might mean spending more or having to wait for an order.
