Due to how new these parts are, your best bet aside from eBay is an Apple authorized repair store. Not an "Apple Store" but an old-school Apple repair store. These stores are great because they can order these parts in and you won't be interrogated heavily. Heck, the staff may give you pointers! It will cost a bit, but not as much as a new display.

Sorry to hear your 23" go out.
