It all depends on what kind of travel you are looking for. On my street/urban bike I use a Marzocchi DJ series 100 mm fork and use a stiff spring to stiffen things up.
You may like ridged, I have friend that have gotten tire pressure down to an absolute science, and they say if you get that right, you dont need suspension on a trials/urban bike.
Another option would be the Rock Shox Argyle RC. It offers a little more adjustably over the Marzocchi DJ and is around the same price. (depending on wether u want Argyle RC or RCT.. the RCT is significantly higher.
As far as rigid goes, I have many options there as well... I'd recommend a DMR Trailblade 2 Rigid Fork in that category.
