Thanks I think I'll send it to Germany to have it retipped

Hi all, I've been restoring a Beogram 4002. It's working fine now but the MMC20E head is too old and I need to change it :( I couldnt find anything cheaper than $500 for a MMC20S. Is there a way to get a new head for less? Does someone has a solution to use a standard, cheaper head and adapt it to the harm ? Thanks for your help
