GMail Notifier replacements

I never really liked the official GMail notifier for the Mac for the following very simple reasons:

1. No Growl integration
2. Support for only one account

So, what are the alternatives?

1. Gmail Notifr
2. Notify

Plus points for both are the negatives of the official app which means support for multiple email accounts and Growl integration but i guess i'm leaning to #1 in the list for two reasons:

1. Google Hosted Apps support (even though the developers of the Notify app said v.1.1 will support Google Apps)
2. Open-source

If you have any similar tool in mind feel free to write a comment :)

Cheers
