I got one of these a few weeks ago on Feebay, and WOW. Proper brilliant, much better off road than the E3, light, easy to use, back seat is bigger... definitely brilliant.
Small quibble would be that the seat doesn't recline, so small boy looks a bit squished in the front when he sleeps (the back is positioned slightly more reclined.)
Anyway, if anyone likes the P&T but needs a little more ruggedness, I would deffo get one of these.
