I am looking at replacing the saddle on my commuter but I really have no Idea where to start. I realize that many of you will recommend a brooks, but I a concerned about dealing with caring for the leather.

I have a 20 round trip commute and ride the occasional weekend tour, usually less than 75 miles at a time.
I am a student with a full time job, so I ride from my house where my garage stays in the garage to campus where it is parked outside for several straight hours, then to work where it stays outside for another 6 to 8 hours. The exposure is the main reason for my concern about the Brooks

I ride a cross check with a fairly aggressive posture so I am leaning towards a road saddle, but I need something That I can sit in for 50 or 60 miles if I head out on a long weekend ride.

I am trying not to let price influence my choice so I am game for just about anything that will fit my needs.

I almost forgot I am 6'3" and 250 lbs, I don't know if that has anything to do with saddle fit, but there you go.
