Gotcha. For your needs and wants, the Peregrine makes no sense.
Pricing also appears to be different. I only saw eBay pricing for the Crest. The Genesis version was around $300, and the Deep6 version was a little cheaper at $275. Really hard to go wrong with just about any modern dive computer. It just comes down to features and capabilities that the diver wants.
It's like anything really. I get people asking me why I bought a Perdix. My reply is because I wanted one. I don't think the OP needs to have his reasons for going with the Peregrine challenged by those who don't want to spend the money on one. Anyway he bought one now so all other answers are moot.
