B&K Television Analyst

[user181]

In another thread, it was recommended to me to use a B&K 1076 Television Analyst. I do not have one, and have looked on eBay at the various listings. I see models 1076 and 1077B; is one more desirable than the other? It seems that the difference is that the 1077 is a later update of the test set, but I wonder if one is nicer than the other in terms of usability, etc.

Also, as with anything on eBay, I know the buyer must beware. So, I'd be concerned about getting one that works and that I'd be able to trust to give accurate results. What do you guys typically do when getting test equipment from eBay? Are there any resources for getting the test sets tested & calibrated? Or, are there better places to look for purchasing test equipment?

Thanks for any advice!
