Recommend a good address book/contact manager

[imported_BIOSMonkey]

I recently had a NAS drive blow up that contained a database of all of our contacts and addresses. For several years, I've been using an Access database with a custom entry form to manage this stuff. But now that the worst has happened, I would prefer to switch to a dedicated app. Features I need include custom field creation, name searching as I type, export to file formats compatible with Word mail merge, and preferably some sort of auto-backup function that would let me write a second copy to a different location. I'd also like some integrated calendar functions....(mostly for printing purposes rather than planning).

There are about a million different address book apps that probably do most of these things to some degree, but I'd like recommendations on something solid, configurable, and from developer that will maintain it for awhile (ie it should be one of their top-shelf products).

Thanks for any ideas...
