Just getting back into the electronics hobby after 50 years. (Tube era, fixing old Emerson TVs). Have scope, signal generator VOM etc. Hobby includes Arduino, breadboard transistor circuits, 555 timers, logic chips. Lots of learning.

Have probes but need a list of 'must-have' connectors such as: BNC, BNC TEE, BNC to pigtail, BNC to banana plug, what else ??
Need to order on line and to save on shipping I would like to be as inclusive as practicle.
Any lists would be greatly appreciated.
Thank you!
