Based on reviews and whatnot, I've ordered my first router combo set. I'll be using the fixed base with my homemade router table. I have seen some reviews mention that it may not be a good idea to use the DeWalt 618 under a table as the variable speed may go out. Does anyone know when the 618 first came out and if DeWalt has made any modifications or changes since then?

I've had one of these for close to 20 years. I am a diyer so it doesn't get used every day. Part of the speed control system is a Magnet Ring. My Magnet Ring broke recently so I started looking into reviews, as you are doing. One comment I found was that using this router in a table was not a good idea due to the direction of air flow which would result in a dust build-up inside the router. I'm not sure if this would contribute/cause the speed problem. When I opened my router to replace the Magnet Ring it was pretty dust free. I do vacuum it every time I use it. I have a dust collector hooked up to the fence on my router table. Based on my experience I will continue to use my router in the table.
When I have seen comments on Speed Control problems the first response seems to be the Speed Control Unit. I haven't found a lot of info on the Magnet Ring so I'm wondering if some responders don't know about it.
I've contacted DeWalt on several occasions and the reps don't provide much info. They usually say to contact an authorized repair center.

I'm wondering what model you have. Have they been making the 618 that long? You'd think they would have tweaked some things if they had users complaining about a consistent defect. Although, 20 yrs out of your router is pretty good.
