Finding Rentals

Is there a website which makes it easy to find a rental in a city and/or
at an airport of your choosing? The plane I trained in was fine for
training but it's a well used trainer. For local flights, I'm okay with
using it but for some longer flights I'd prefer to rent something else.
The flight school I'm at does have other craft, but not at prices I'm
willing to way. Besides, most of those "other" are complex and I do not
have my complex endorcement. And so, I'm left wondering if there is an
easy way to locate planes to rent? Any such site?
