I would take up the offer of danielhuw before you leap into buying one of these Kreg tables. Perhaps his is a better quality build than mine.
I bought the Kreg table, fence and stand from Axy about three years ago and was quite pleased with it to start with but I can safely say that I wouldn't buy another one.
All was well until I had a bash at jointing on it by offsetting the outfeed split fence – a fairly clever system is used. I noticed that, instead of having nice straight sticks, they were actually bowed. Having returned the fence to its normal flat profile, I then put a long straight edge against the fence. Oh dear me. It turns out that the beefy extrusion isn’t straight! It veers off by about 2mm from the centre (where the cutter slot starts) to the end of the fence. No amount of trying to straighten it in a large record vice has worked, so I glued on two strips of very thin copper sheet to shim it out. This was only a temporary measure as I have now made and fitted a one piece oak fence that has several allen key adjusters on it to make it straight.
I've had to shim the underside of the top to get it somewhere near flat. I don't remember it ever getting wet but it has definitely bowed over the short time i've had it.
The other problem I have had with the table is with the insert plate. I seem to be forever having to level it. If the workpiece isn’t catching the insert plate then it’s catching table. The levelling system seems bomb proof enough but I think the insert plate isn’t robust enough to be completely stable.
I would save your money and have a bash at making your own. There are loads of utube vids, downloadable plans on t'internet and some great builds from members can be found on this forum.
