Yeah    a reseller will say price is 775 on a s17+ unit thus no trump tax, but I simply am not interested in doing business that way.

There is a big issue  of owing a lot if it gets found out.

Lets say you order 10x 2000 dollar units    20,000  tax should be around 5500.   you pay  much less 500.  Then 10 months later you get a huge bill for the gear.  5000 or 6000 bucks.  I don't need it hanging over my head.
