There is no one stroller that will do everthing, we ended up with 3 and use them for their best functions. Buy the lightest one that fits your purpose but make sure it has big inflatable tyres, more on this later. Also look at how big you are and family history of baby sizes, one size may not fit all.
1. Bugaboo Frog (and all the accessories Chf400 from Ricardo) now 8yo, it is getting a bit loose in the wheels but all the fabrics look as good as new. Was used as a jogging stroller for the first 6m (2x) so the little fellas could lay down while my wife ran.
+ves Very easy to push and manoverable, durable
-ves Every yuppie and his poodle has one, price - secondhand is worthwhile looking at.
2. Quinny Zapp, travel stroller at it's best, folds to nothing can go on as hand luggage on a plane (but pack it up in the departure lounge or the "helpful" staff will stick it in the hold, depends on the airport where you get it returned to you). Ours has been everywhere, we pack the maxicosi baby car seat full of nappies + baby milk powder, wrap in several garbagebags and duct tape for our flying holidays, then we always have a safe car seat whereever we are.
+ves Looks cool, price, highly manoverable, lightweight 6kg, adapters for maxicosi baby capsule.
-ves wheels are a bit small for rough ground, can fall over with a heavy bag on it when you take your child out, not much room to carry/store things in/on it, not really durable enough for an everyday stroller.
3. Koolstop jogging stroller
http://www.wayfair.com/Kool-Stop-C447551.html our has done an estimated 6/7000kms through Swiss forest (disclaimer - my wife is a mad keen runner). Paid AUD300 6 years ago and thought it was a bit loose and flimsy new, well it is still loose and flimsy and going strong. The only problem we had was the rear handle mounts (plastic) broke (-15c running through snow


) so I fixed it with an old ski pole and a few screws. Has 20" wheels so will (and has) go anywhere.
+ves Cheap, easy to run with - well balanced, tracks really well (3 wheels are permanently locked), lightweight, packs up easily and wheels come off so would easily fit it a small car boot, loads of carry pockets and storage underneath, go anywhere with 20" wheels, seat is hammock style so the baby's back is well supported, huge sun shade.
-ves The looks I get riding my bike while the missus is jogging with the stroller


, the brakes are not so good but there is a wheel strap for complete safe parking on hills.
