Index controller trigger snapped off while doing a stupid joke. I'm outside of warranty and valve isn't offering a replacement so I'm thinking of selling it for parts and using that as a discount for a new set of controllers. What's a good price to offer on ebay?

here's the damage:
left controller's control stick's neutral well is way too wide due to constant use so it drifts sometimes.
right controller's control stick has popped right off, and the ribbon cable inside has ripped. The nub still works but there's no way to do stick press inputs.
The trigger is broken and would probably need to be repaired with some kind of glue.
