FWIW I have been very happy so far with my Hammer N4400 with the ceramic guides. I thought a lot about going with the Felder FB-510 when I bought my N4400 as it was on sale for IIRC $600 more, but I decided not to as I felt that it would just be more saw than I needed. So far I havent needed anything more than my N4400 for what I do, but I do sometimes wish I would have spent the extra money on the FB-510 just because. That said I like Hammer/Felder a lot and am hoping to purchase a Hammer A3-31 12" jointer/planer combo sometime next year funds allowing.
