Looking to by a new tick tracer

I have been through about 4 of the Greenlee ones, the stupid end cap/on-off/battery holder keeps springing off and getting lost. Clever marketing maneuver on their part - they got me to buy 4 of em.

Saw the Fluke model at Cooper Supply - has an on/off button which looks nice. I am generally pleased with Fluke's equip in general.

Anyone have any recomendations?
