Looking for new bike computer...

Figured i'd poll the tri community before I decide which computer to invest in. I'm currently just riding with my phone in the jersey back pocket with Map My Ride running. It's been great for tracking distance, average speed and miles ridden. I'd like to have a display on my handlebars so I can view distance a bit easier and current speed. I'd like the computer to be compatible with an indoor trainer, have some heart rate capabilities and be able to log on my phone. What would you guys suggest? Thanks for any thoughts :)
