I recently went to the .30 Wildcat for my small game hunting application. The reason I picked the Wildcat over the Dreampup for 2 reasons, tank size and cocking action. The Dreampup cocking action seem to be a bit far back for my taste. The only thing I wish the Wildcat have is the reg gauge.
For overall performance and price point, the Dreamline would be a great gun to own in anyone's inventory.
