Where are people getting screens for this device?

I let my phone fall on some tiles and shattered the screen and cracked the back glass.

I've been looking around on Ebay and Amazon and screens for this thing are actually almost as expensive as the whole used phone. I can get a whole used phone for $75 on ebay and I can buy a guaranteed fit screen for $45 on ebay. Is there another place I should be looking for a better price on an LCD display with a frame, or should I just buy another phone and transplant the screen and frame? I don't want to lose out on all the embedded data and login information in my phone, or else I would just migrate to a new phone without looking back.

Buying a whole phone also would let me replace the back glass cover without needing to buy another part.

Or is it easier to transplant the internal components that make my phone mine into a new phone and discard most of my current device?
