Why do I see more Vandersteen model 3s vs model 2s for sale?


Just wondering about something I've noticed on the audiogon.com website over the past few months. It seems when Vandersteen speakers pop-up for sale a good percentage of them are the model 3's. Based off what I know about Vandersteen it seems like there should be a lot more Model 2's for sale based off of overall units sold. Anyone else notice this? What could be the reason?
I currently have the Model 2c's (SNs around 27K, I believe) and they are a great speaker. When I upgrade I either want the latest version of the model 2 (2ce sig II's) used, or used Model 3a sigs (also the latest version). I think the pricing would be somewhere in the ballpark of 1.8k for the 2ce sig IIs vs around 2.4k for the 3a sigs.
Would I be better or getting the model 2's or springing an extra $700 on the model 3's?
Just wanted to get some input on this. 3A sigs seem like the logical choice, but seeing so many for sale compared to the model 2's make me hesitant. Thanks for any insight.

Many moons ago I upgraded the 2ce to the 3a ( both non signatures) and I preferred the smaller 2ce. I just never enjoyed the 3a and sold them after about a year.  If you like the 2c's I think the signatures would be a better choice!
Thanks for the input. what didn't you like about the 3a sound compared to the model 2?
If I were to do it again. I would just buy a pair of used Quatro's, but being less than affluent, I would suggest buying a pair of used 2wq subs for your 2c's. That would give you 80% of a 3a sig. (Also, the 3a sig Sound Anchors stick out and make positioning difficult in cramped areas).
When money comes available, you can do what I did, buy a pair of Treo's and keep the 2wq's. That way you will get 90% of a Quatro. If you can find a pair of Treo CT-even better.
Vandersteen is coming out with a new sub system, so prices of the 2wq's will probably be coming down. In any case, the 2wq's are no slouch and integrate seamlessly.
