I bought a Baby Station a few months ago and it is definately well worth getting. I thought that once my son could sit by himself, we wouldn't use it much, but I still use it all the time. Its good because apart from knowing he won't fall or get out, he can reach all his toys, so doesn't get bored quickly.
You can get bogged down with all these fancy activity stations, bouncy chairs etc, but I think something like this is a more practical buy, because its a lot cheaper and you don't rely on fixed toys and it doesn't take up loads of room. The quality is excellent, it will keep well for next baby or re-sale.
