Can't really go wrong with an aluminum Tada68. They're not very fancy or anything but they're well-made, easily available, and not too expensive. You could also get the Tofu65 which uses the same PCB as the Tada68...but I don't really see the point. I mean it does have a brass weight and those are all the rage these days but it's not like that Tada68 is light or flimsy...it's thick aluminum and surprisingly substantial.
For a bit of a different form factor and more lighting options there's also the Clueboard which is readily available. I have an acrylic sandwich one which they don't actually make anymore but I like it...the aluminum ones should be nice too. They're a little pricier though.
