we have both those FP items for the girls. the phone is in shops still (called the chatterbox phone) and you can get them all over the world and not expensive (they sell for $10 here = $7.50 US) and the activity centre was a hand me down from a friend but there are tons of them on ebay in Australia so they must be available somewhere for there to be so many on the market. our daycare centre alone has 3 of them hung up for the infants to play with.
E.T.A. - the one in the epinions link is the exact one i have and if you really want one and can't find it locally PM me and i will send you mine if you want to cover the international postage (no charge for the activity centre) I was planning to donate it to our playgroup (we are trying to clear out things and although both girls still are drawn to this simple toy, we need to let it go) so let me know katriona and we can sort it out for you (not sure if it is worth the cost of international postage though)
