Query: Oily beans killed my unit!

I got 3 good years out of this grinder, but there are more minuses than positives. It is consistent, easy to use and very inexpensive compared to many others. The immediate downside for me is that you have to hold the power button on; very noisy compared to others; and this unit is easily killed by fresh, oily beans. I have ground dozens of batches of inexpensive, store-bought beans with no problems. I did 3 batches of freshly, French roasted beans and the unit died. Cleaning & rescue proved to be too difficult to justify more hours, so it is headed for the junk pile! I have had a DeLonghi unit that's much easier to use and is twice as old and a smaller foot print, but i will have to beg to get it back. Using a blade grinder on the oily beans is my only choice now. Actually, I use a French press for brewing and a blade grinder is sufficient, imho.
