Poll: MI 6010T or Guildline 6622A-XPS - Better performance with modified 9975?

[Certi-Cal]

Hello calibration world 

2 questions.  Given the opportunity to purchase a modified 9975 Guildline Current Comparator Bridge (CCB) or a kit to modify your own - if you could achieve better accuracy than any commercial bridge at 1:1 & 1:10 ratios except a cryogenic detector CCB;

(1)    What would you consider a fair price for kit/modified bridge

(2)    Who might the target market be?


Please keep in mind the newer units self-balance and the 9975 is strictly manual, requiring meticulous attention plus extrapolation.  Just for reference, the last pricing I could find on the 9975 was $54,000, year unknown.  I don't know the current pricing on the 6010T or 6622A-XPS (please chime in if you do!).

"Bonus Question"  ---   If modification(s) included easier balance and ability to use unattended in an environment without temperature control, how would that change your answer to question (1)?

Thanks All!
