Upgrading from Photoshop Elements 2 to El 3 ought to be a no-brainer (16 bit, Raw converter, CS type interpolation), but there are web reviews reporting bugs. Is anyone using 3? How was it for you? What are the shortfalls against CS? I know about lacking curves. Any downsides in buying the unboxed version on Amazon for £25? No manual, but is the manual worth having anyway?
