Hi Harry,
Having spent an age researching the same thing a couple of years ago I came to the conclusion that I had to spend a bit of money to get exactly what I wanted. I had previously owned a couple of not cheap-but rubbish router tables. The main problem been
A)the flatness of the table and the insert. Even a dip of just 1mm can really cock things up.
B)the ease with which you can change the bit, i.e easy access.
C)the ease of height adjustment. The joy of hunching over the table-top whilst trying to force the router upward to reach an exact point is really short lived, like 2 seconds. Either make sure your router has fine height adjustment or that you can raise and lower the bit via a mechanical mechanism.
D)the use of mitres fences can be a
lot more tricky than one thinks, especially when trying to control end cuts on long pieces. A well supported piece is a godsend so a BIG table is preferable.( but not so big you get a bad back)
E)the fence can be basic and very effective. However a fence that has an easily changeable aperture for the router bit is far safer with pieces less likely to be sucked into the gap and dust extraction is more effective.
After all that I ended up biting the bullet and going for a Jessem outfit with all the bells and whistles.
Got the Jessem table , Rout-r-lift, Fence and the Mitre-r-slide ( mitre gauge-absolutey brilliant.)
I could not be happier with the result, with tool downtime at an absolute minimum!!
I use a De Walt 625 EK (2000kw) as the motor.
The total cost for that little lot was just over a grand. And considering how much use I have had out of it , with the minimum of problems, that was money well spent. I built a table to stand it on and included its own sub table dust extraction, and the usual drawers for all the accessories.
Check out rutlands.co.uk for more info.
I should state though that I work wood for a living and therefor any money spent on tools is tax deductable and therefor a little easier to swallow,just!
good luck, hope that was of some help.
Decklan.
