While I dream of the day that I get to buy a more serious tablesaw, I currently own a Ryobi BT3000. While it has its limitations, it has been very useful over the last six years. Of course, it cannot really take advantage of a lot of jigs and such that rely on the miter slots in standard tablesaws.
I have heard of a miter slot attachment put out by Ryobi. Here is a picture of a left and right one installed.
