The Pentax-M 100mm f4 macro is not exactly rare. Many copies have sold in Flea-Bay over the last 30 days bringing between $50 and $200 with the average being around $100 USD. I would suggest you certainly don't need it if you have the excellent DFA 100mm Macro. The M is a great bang-for-the-buck lens, getting comparable ratings by users as does the DFA, for roughly 1/4th of its' selling price.
