@Arna you don't say what cost you want to be lower than, so I'll assume that you're trying to avoid cloud service provider costs.
If you're looking for a solution that would allow you to run the CDP Data Center 60-day trial on your own, local machine, consider @carrossoni 's Vagrant and Virtualbox-based approach, which you can read about here:
