Replacement for TC15 - need recommendations

Hi folks, it looks like the microswitch on my TC15 has died. I’m pretty out of the loop on new lights lately, any recommendations for this form factor or smaller w equivalent output? Need a new daily carry

PS: would consider double 18650 if its decently thin

Budget?

The Thrunite TC15?

It’s still available. Just looked, <50bux at Amazon.
