Vienna is not too expensive.
You have Special Edition Bundle which is very affordable for what it contains. Vienna Special Edition Standard is 345€, Extended 465€, and if you buy both in the bundle it's 810€. You have Special Edition Plus, which are additional articulations, you can buy that later on if you have the need for it. Plus Standard is 445€, Plus Extended is 390€, Plus Full (both at once) is 835€.
This is all very fair pricing when you consider the quality, flexibility, and the engine it contains. Don't be a cheapskate, if you want the real deal, save up for it
The basic Special Edition Standard contains a lot of really useful stuff, and costs about the same as AD+Retro ADpak.
You don't have to buy the Cube (9200€), you know
