IPhoto 8 alternative

I kind of like iPhoto 8, but it's unmantained, is there an alternative that:

• runs on 10.6
• imports iPhoto library (events, albums, Facebook albums, hidden photos), and works more or less like iPhoto itself
• is actively mantained
• if it's not free, it offers an almost-fully working demo, i.e. limited in time but not in features (to be sure it actually works)
• if it's not free, it has a reasonable price (i.e. 5~15€)

My problem with iPhoto itself is that the newer version requires 10.7, and the version I'm using has some very annoying bugs, such as every time I click on a Facebook album, it resets its privacy to "friends only".

(likely such a software doesn't exist, but searching for such a topic brings up such a mess that I'm not sure, it might be well hidden)

If you know of a program which doesn't have all these features, but have most of them, feel free to list it anyway (no Picasa).
