I am not going to tell you what to buy. There are a lot of good professional reviews/shootouts on routers on the internet. I will say that I recommend building the biggest table you can afford/accomodate. I started out with a small table and now it just sits in the coner of the garage, waiting to be recycled into something else or taken away by a lucky woodworker who needs something to start out with.
I went with a 27"x43" top this time. The Incra fence systems require a lot of extra table top space. I have limited space too but a large size table did not worry me. My plan is to use every available inch of space below the table to store my routers, templates, manuals, bits, fences, stops, sleds, miter gauges, depth gauges, PRL tools, etc. This should provide plenty of storage and with wheels on it, should prove to be more than flexible enough to merit its presence in the workshop.
I also like a router table that sits higher off the ground than most tables you can purchase. I like my work to be close to chest high. I can see better and I am not hunkered over the table all day. This too makes for more storage space. I can not wait to finish my router table so I can consolidate all of my tools for the router in one place. In the end, this should actually free up a lot of storage I am currently using elsewhere in the garage.
And lastly, plan ahead. Inevitably, you will want to upgrade if you do not have the funds to buy the best right now. Keep this in mind when building your table so you won't have to start over when making upgrades, like I had to.
Happy Holidays and keep ups posted on what you decide to do!!!
Just remember what my father always said, " Half the people in this world are below average!", and everything in life will make a hellova lot more sense.
