I have all of them and I bought them when CW made offers I couldn't refuse.
They are remarkable and very useful. The thing to notice is the PC2A or CA2A are being discussed an awful lot. They are being compared to the hardware units and other emulations. In either case the overall conclusion is very favorable.
My real love is the CL. I find I use it often because its simple and it works as it was intended to. I also bought the update for the PC2A. So I have a very high regard for them. I will not insult you in saying I would pay the full price for them because I don't know for sure that I would. However, I do believe they are worth the asking price and a lot more.
I am very pleased with all of the CW PC modules and I would recommend the extra cost ones with no reservations.
This does not include the Soft Tube modules because I have only the one that came with X1 Expanded. It is very good though. But I can't comment on modules I don't have.
