Thanks girls... I think I'll go for it. Money's not the issue, it's just the resources and the waste that gets poured into creating things that hardly get used - i have enormous guilt over this! But I have a sister and brother who are yet to reproduce, maybe I could pass it on to them and that might assuage my guilt somewhat?!?!
I used to have a reversible one from my nanny days, and was pretty happy with it (currently the in-laws are using it in Melbourne) so I've been looking at a few of those.

But there's a whole other thread in that....
