Right now, you can score a pair of Performance Century Shorts for about $25 on sale. They really are OK shorts (not the gel ones) and really made a HUGE difference in my comfort level.
A pretty cheap "trial", and probably the best bang for the buck as a trial pair. Buy them tight. And remember to wear them commando.
As soon as you start wearing them, it will get better every day.
Just got the flyer in the mail - on line, or in the store.
