You know, borrowing a stroller is a really great idea. Also, it gives you an opportunity to see what features you like/need before slapping down the credit card.
Ooh, reasonable priced, huh? Well, it all depends on what you expect from the stoller. The best one I've found is the Dreamer Design Rebound Light. It's about $250 though (yikes!) but you can walk or jog with it easily. The woman I work with swears by the Mountain Buggy Urban, but it's about $400! Target has a decent stoller for about $100 - the Baby Trend.
