Nashbar has some outstanding bargains for saddles under $30. Check out the Selle Italia Q-Bik SE. Or one of the lower priced saddles.

Too wide can be uncomfortable. I recently switched my road bike from what it came with -- 165mm wide, padded, Turbo style -- to a 130mm wide Selle Italia SLS Kit Carbonio with longer nose and minimal padding. Much more comfortable, although in part it's because of the new saddle's flatter configuration. Never could find the sweet spot on the other saddle. Turns out my sit bones are much narrower than I'd realized, so even the more common 140mm or so saddle might have been too wide for my road bike, but possibly appropriate on a hybrid.

But the old saddle is now on the hybrid with a more upright riding position, where it feels pretty good. So it may replace my previous even wider, softer saddle on that bike.

Some of my friends ride Brooks Cambium, no padded shorts. Doesn't seem to me like it would be comfortable but they all like 'em. Most of their rides are casual pace, maybe 12 mph, around 10-30 miles. Cambiums have no padding, with a firm fabric coated rubber that's supposed to mimic leather.

I'd be tempted to buy two or three of those sub-$20 saddles on Nashbar and try 'em out. The 4ZA Stratos and Cirrus have two of the most common variations in saddle configuration now. Cheap way to find out which seems to fit better as a guide to considering a better saddle -- unless the 4ZA was fine as-is.
