I have one uploaded on the sims exchange. If you're interested, I'll post the link. It's a tiny island, made pre-Late Night, all lots are +100 Beautiful Vista moodlet, the biggest residential lot size (I believe) is 40x40 - you can always delete and place lots in Edit Town, all rabbit holes and spawners are included. Spawners include the fish from World Adventures, but not the gems or insects as I don't believe they actually work outside of China, Egypt, and France.
I thought you might be interested because you say that BP slows down your game -- this one should run smoothly on any system because it's so small.
