You definitely want one with proper dustextraction. Mirka is a reputable brand in this segment of power tools.
Like @koendb says, if you've got the money, Mirka Deros 5650 is the bee's knees. If you're looking for something a bit cheaper then Rutland's do a reasonable alternative.

I might be a bit late here.
I have a Mirka DEOS - the smaller one. It is beautiful to use. It costs though!
I wanted a bigger sander as the Mirka is really a finishing sander, but couldn't justify the cost of a Deros so went with the Rutland 125/150 sander. So far I am impressed with it. It does the job. It's not as nice to use as the Mirka, but it is a lot cheaper.
