@Hondo Welcome to BassBuzz!

If you want to return the amp and trade up, I say go for it. From someone who has worked in the retail industry, that is exactly what the return policy is for. If the person that handles it acts any differently, they are not representing the wishes of their company.
However, different amps can have different sounds and I would highly recommend going and testing the 200 with your own ears before deciding to change.
