My 31LE was came from HK.
If you chose silver lens of 31LE,you can get cheaper price in HK.
However,I remember PENTAX in HK has changed agent.
I don't know if they will change lens price.
Anyway...31LE is a good lens for me.
If you don't like change lens.I suggest you directly buy 31LE.
Or you just buy FA35mmF2,that also has good appraisal ^^
