Turntable upgrade

I currently have a EAT flat turntable with an ortofon black cartridge and always liked it.  However my beloved grandchildren, two and four, felt a need to help papa with his music while he was at work and ripped the counterweight off the tonearm.  The question is do I take advantage of the damage to 
1. Upgrade the tonearm and if so I will take suggestions (budget 1,500 to 2,500)
2.  Repair and upgrade cartridge (stylis may be damaged as well)
3.  Trade my grandchildren in for cash or sell them to the gypsies for magic beans.   

Thanks, temporarily digital only
