Hey guys, sorry for the non-immediate response, I'm not getting any email notifications of replies to this thread.
Anyway, yes I went with the rubber upper mount instead of the full-on pillow ball since the car is street driven and the roads suck around here.
I did go with KTS and duty was less than $70. Here's the rub. Different states have different tax rates. I used this link to calculate potential fees.

Given the feedback for KTS on the Ebay site was very good, I felt comfortable pulling the trigger. Their English is not the best and it usually took two days for a response but everything came out fine in the end. It helps that you know exactly what you want and have done the research. Really technical questions don't get answered to your satisfaction due to the language barrier.
