How can I get an official 3.5mm adapter?

[Essenar]

I purchased my Mytouch3g unlocked off a private seller and it works great, but he didn't have the 3.5 mm adapter anymore.

I need to replace it so I can listen to my music but I don't want to use a generic brand one as I've heard they don't play nice with modded roms.

Does anyone know where I can (preferably not expensive) replace the 3.5 mm adapter OEM from HTC?

ebay or htc's site quality varies htc will be beter but they cost, in the end i went with an A2DP headset as it was cheaper.

i have these, they work great and i can charge and listen to stuff at work
