I find the main problem with UVWrapper is that the only way to rotate the map is to drag vertices individually, but the program is far more powerful than it first appears, for example, you can do a box projection, then box select, for example the top projection, or part of it (Not very accurately, admittedly, but hey, it's a free program), drag the top projection over the bottom projection any old how, box select them both and then ask for a planar projection, and hey presto, the vertices are lined up correctly and everything, and you have the top and bottom projections layered on top of each other, thus saving BMP space

(With the obvious downsides, but hey, it's only an example).
Lithunwrap I didn't get along with, but then, different horses for different courses as they say
