Welcome to The Router Forums.
Selecting the best router for your use, and a particular table isn't as simple as choosing between a few different models.
The price paid for a 'router' can be as low as $20.00. Some industrial strength models cost more than 10K.
I have three older models myself, that cost me about 40.00 each. They all spin a bit that cuts wood, but don't offer much at all in the 'features' contest when compared to newer routers. I don't use them that often, so I am fine with that for now.
If I wanted/needed to use my tables on a regular basis, I would get tired of the lack of features in this order:
1. Ease of Bit Height Adjustment
2. Ease of Changing Bits
3. Ski Friendly Base (for use outside the table)
4. Plunge Base (for use outside the table)
5. Built in Speed Adjustment (I use an external speed control)
6. More than 2.5 HP (the bigger the bit, the more HP you want if the wood is hard)
Shank size is also a consideration. Generally speaking 1/2" is better, but there are some smaller bits that only come in 1/4". Some routers are sold as being able to use either size, and there are third party "adapters"....but I don't use the adapter because it adds a second 'friction' sleeve between the motor shaft and the bit
Higher end routers that do both sizes of shafts, have two (ore more) different 'collets', one for each shank size.
Noise produced by the machines can also vary a great deal if that is of concern to you, but in general they are all louder than I care for.
Good luck in your search for the right machine for you!
I am planning on purchasing a router table from Sommerfeld. What is the best router to mount on a router table?
