I also have a FT2000e, mounted in my work bench. When the collet nut split in half, not sure why and very disturbing as it happened during a cut, I searched for a replacement. No replacements available for this router, maybe used stuff on ebay. I found that Musclechuck makes a collet replacement that is very superior. And there are collet sizes available for 1/4" and others. I also installed a RouterRaizer mechanisim to raise/lower. This is another good product. Neither is inexpensive, but as I really like this router, they allow continued use for less than the cost of similar new router. Hope this helps.
I am in no way associated with either of these companies, just a satisfied user.
