Thanks for seller vote, will look some more but wanted R300 for full scale HP3478 ranges to start (set of 10/12 makes 30, 50, 100,150, 300,450, 3k and lots more). Hoping to start with at least 0.1% and then test/match for tighter. Did not see US shipping for $6 which would be fine. Still looking for better way to series/ parallel them selectively than banana plugs.
