You get the design, the branding, the code (it's a Rails app), the customers, and the steady cash flow.
You'll lose the branding, unless 37Signals decides that it'll keep linking and promoting it. Potential buyers and clients are coming from 37Signals; and that's why design firms are putting a high monthly fee on the product.
The design and code are by no measure worth $480K. The clients (and steady cash flow) will go with clients. Expect a cash flow crash by losing the branding, and also changing the payment system.
