They were claiming (sales person) to give us a credit for the whole reflash when the other came out not $150 bucks off.Nobody put a gun to your head and said to purchase it!
I don't think it would've been a realistic expectation to have most or all your reflash amount refunded to you. Plus, development rumors have been floating about for the Si version of Kpro for months, years. It shouldn've been a dramatic surprise that they were planning on releasing one. It's not as though they were deceiving or forcing you into buying both.
