Hi! My friend replied as follows:
Hi Khai-Wei ,hope all wentwell with your Convention . . . . Re Kn1400 approx value around $900.00 or the 920 ,not a good choice ,key action is quick togo and were only in the range for around 6 months and then superceded by 930 ,value $600 max 930sadly suffered from the clanky key Problems of the920
I hope that this will be useful to you.
