Re: high speed spindle (was no subject)

Good advice. I've been looking at the Dewalt DW679 and the
equivalent Porter Cable trim routers for this use. Anyone have any
suggestions for brand? Since all that I've seen have 1/4" collets,
anyone know if 1/8" collets that that are sold with these company's
RotoZip exuivalents would be likely to fit their trim routers?

Thanks for your help,
Jeff
