When I used to shoot with my small Point and Shoot an inexpensive $10 tabletop tripod came in very handy for long exposure type photos. These you can throw in your small gear bag without much effort or sacrifice in space.
Now that I own a much heavier Canon 1D Mark IIN I needed to upgrade to a more sturdy table top tripod.
Bogen/Manfrotto 3007 Mini Tripod w/ 482 Mini Ball Head.
It runs about $49 but it is VERY stable for my hefty dslr!
The foot print covers a lot of area keeping the CG nice nice and low.. as opposed to my $10 cheapy that didnt have much spread and always felt like the setup was gonna tip over.
