I switched to Cubase when Sonar went under. Last time I built my DAW, I didn't even install CbB. I'm just here for the deals.
Will always have a soft spot for Sonar, this forum really got me started on a good foot.
Zinc - I don't seem to have it either. I don't have the .vstsound file - all I remember is I paid $10 to upgrade to PadShop Pro. Maybe that upgrade didn't include it....
I have all the Groove 3 courses you list here. Pretty decent. They just had a "Cubase" sale a week or two ago where everything was half priced.
I have this as well - much more in depth.
