What is the best mail migration utility for Mac or on the web?

I've used GMail's auto-migration and Mac Mail's "select all and drag and drop to other mailbox" options before but are there any other free alternatives that work better with less bugs and failures?

    For migrating to Google Apps Business Accounts from Outlook, Exchange or imap:

    Bulk Exchange Mailboxes and imap -

    Client-less Bulk Exchange Mailboxes and imap -  (limits to 6-12 months of historically messages!)

    Outlook Client or a few PST files -

    Migrating from all other local mail stores or to free Gmail Personal accounts:

    1. Use EmailChemy or other to get your messages into a MBOX standard format.

    2. Use Thunderbird and their IMPORT/EXPORT Add-In

    3. Use IMAP with Thunderbird to transfer messages/folders. Thunderbird works well with Gmail and can handle waits and re-trys.

    Emailchemy converts email from the closed, proprietary file formats of the most popular (and many of yesterday's forgotten) email applications to standard, portable formats that any application can use.  These standard formats are ideal for importing, long term archival, database entry, or forensic analysis and eDiscovery.

    Thunderbird: Works well with Gmail IMAP to upload and transfer messages.
