"I am I am confused model 1 or 3 ?
the sound anchors are essential for 3 IMO"
He's talking about the original version of the Model 3. The Models 1, 2 and 3 all come with the Sound Anchor stands. (At least that's how its been for quite a while now). Without the stands, you can't set the back tilt, and its very important if you want the speaker to sound right.
"I have heard the more recent 3a Sig. and 2CE and appreciate them very much, but my concern is that the Original Model 1 is so old and outdated that it might not be a prudent purchase."
I would call Vandersteen and see what they think. There's been many upgrades to the Model 2 and 3's over the years. Owners of these models are able to send them back to Vandersteen and have them upgraded. He'll give you an honest answer if its worth it to have an old pair of 3's updated.
