Quilt Design Wizard is also made by EQ but it's a much pared down version (and it's under $30).

That would also be more than enough to meet your needs, and also allow you to test drive some of the more advanced features before deciding if you want to shell out the bigger bucks for EQ7 (or EQ8, whenever it comes out).
