I just purchased a Lunt 1 1/4" solar wedge in the past month.  In addition to a 
wedge being the superior white-light filter, it has the added benefit of 
tunable brightness.  Without a polarizer, the sun is a bit uncomfortably bright 
for visual use, but can be easily dimmed to a better level by rotating an 
eyepiece with a polarizer in it.  During annularity, I am anticipating that I 
will have the polarizer rotated to a brighter setting, since the limb of the 
sun is so much fainter than the center.
