In alpha order:

* ACT is a true CRM, does email, but doesn’t sync like Plaxo, and doesn’t interface with LinkedIn. No support.

* JibberJobber is an up and comer. It is a true Web20 application, allows you to get your data in and out, doesn’t do email, but is more like a CRM for jobsearch. And, the support is responsive. (This is my current front runner.)

* LICM is not CRM, has a harder interface, and is tough to get into. It depends upon LinkedIn. Has support.

* LinkedIn (MySpace for Business) enforces its model of networking, doesn’t allow you to input stuff, and doesn’t make it easy to keep your data. It doesn’t talk to anything else. Support unresponsive for the most part.

* Outlook is ugly, but it does email. (I’ve tried the BCM addon and it was terrible.) Microsoft and support in the same sentence; that’s a joke.

* Plaxo syncs but not much else. (But its vendor never claimed it was a CRM.) Has good support.

* ZIGGS20 is really slow, brain dead, ugly, doesn’t sync, and appears to be a dead end. Data in but it doesn’t come out. No support.
