LCD and Digitizer replacement (compatibility)

I've got a question regarding a Samsung J320VPP. My daughter dropped her phone and cracked the screen. There's about 10% of the screen remaining, the rest is blacked out. I'm trying to figure out what screens are compatible with this device. On eBay there's lcd/digitizer ranging from $28-$70-$80. When I search under SMJ320VPP it pulls up the $70-$80 replacement. If that's the only lcd and digitizer compatible with this phone I'd rather just but my daughter a new phone. I can add a little money and get a new phone and won't have the headache of shipping, disassemble, and reassemble. I appreciate all responses.
