I must disagree with you again, Many PC routers come with the speed control built in and soft start,,the older work horse PC 690 is the only one that needs the speed control box the norm. http://www.amazon.com/s/ref=nb_sb_no....54_346&fsc=11
The newer Craftsman routers all come the many extra items,light,VS,soft start,etc. I will agree the older routers are junk, but they have a place in the wood shop not in the router table, just not made to work upside down most of the time..
The bigger 3 / 3 1/2hp routers are just to big for the router lathe, too much mass, it takes a fine touch most of the time..it's like saying you need to use a shovel on the normal lathe..
the trim router is to small..
The Craftsman router lathe was setup with a Sears 3/4hp router and setup with 1/4" collet..
All I can say pickup one of the router lathes and try it out, if you don't like you can sale it off easy..
Routers don't wear out, they get broken. I had a box of Craftsman tools looking for broken parts that were never found. The Craftsman box hit the garbage can this year, drill, saw, 2 sanders, router! If you have the money to burn, the PC is one of the more expensive routers on the market. On many models you'll still have to buy a speed control which somewhat encumbers hand use. Rather incongruous in my mind.
On your router lathe, the determining factor is the depth of cut. Take a repeated shallow cut with a narrow bit and you can use a cheap trimmer. The wider the bit and the deeper the cut, the more power you'll need. Also if you setup to take a wide swath each cut, you'll need a heavier router. I guess it all comes down to how you work and what you want to do. My suggestion is that you start with a 1/2" chuck fixed base router in the 2 HP range, exclusively for the router lathe. If you can get one that comes with a fixed and plunge base, you can mount the fixed base to the router lathe and use the plunge base for other stuff in the shop. If you're going to go with a plunge router, get one that is fully versatile and go for the >3 hp. If you can find one, an Hitachi M12V is the most versatile but difficult to find now that they've stopped making it. It will work with your router lathe but can also be used for a wide variety of other jobs and is the only router that will fit most of the 25 router methods.
Remember, you do not buy just one router. You collect routers. Each has its own personality and each will find its own niche in your shop.
