We have one of those green and yellow swing sets (you see them everywhere!) and it gets HEAPS of use . Not so much now it's winter, but when the weather warms up the kids spend a lot of time playing on it.

We actually got ours second hand and one of the swing's seats eventually cracked, but my DH luckily found the exact swing on the hard rubbish so we were able to replace it haha! I think it's pretty common for them to crack over time. Being outdoors they go a bit brittle. I think Hills make good quality swing sets, they have a warehouse somewhere in Melbourne and I'm sure it would be very easy to get replacement parts when needed.

I don't think you could go too wrong with a swing set anyway!
