I bought this about a month ago when it was on sale for $199. If you can get it at this price it's a great deal.
I think that its strengths are the huge selection of analog synths which really almost the entire history of synths from the early 70s through the 90s. If you like synths this is a great package.
The "traditional" keyboards are a mixed bag. The VOX and Farfisa emulations are pretty good, but the B3 is nothing special and the Rhodes/Wurlie and acoustic pianos are adequate at best.
What is nice is that Arturia "adds" a lot of features to these emulations that in many cases were very difficult to manipulate (such as tonewheels in B3s or hammers in the EPs) in the originals. It's a very thoughtful implementation. And the thick, printed manuals that come with the package are first class.
I also found its authorization scheme to be one of most civilized and easy to use. You can install them on up to five different devices.
