suggestions for a lawn mower?

I need a lawn mower. My husband passed away in Novemeber and the one we had is big, hard to push and even harder to start. I will sell it but what do I get? I don't mind doing it but need something that is easy to start (electric??), easy to push (self propelled??) but hardy enough to handle some rough terrain. My lawn is a work in progress - more weeds than grass but they are green in the summer and still need to be mowed (actually they needed to be mowed awhile ago). Any suggestions would be greatly appreciated. Thanks.......Laurie
