[JackBauer]

Cant afford a new one but am going to north africa with dd's and my mum in a few months and all flights/transfers are in the late afternoon so I need soemthing for dd1 who will be 3 (dd2 is 15 months and can be carried in a sling so shes ok!)
Any ideas where I can get a cheap battered one? ebay are sooo expensive second hand as well.
Or a decent alternative?

Bumping for you.

thanks! I ahve put a bid on one on ebay that is quite cheap at teh moment but I know it will get expensive near the end.
I just wish I coujld hire one, its not like I am going to use it again for a good while!
