And we used DE+DS, so even less. Having kids was far more important to me than having kids who looked like me -- I'm a plain woman, so that wasn't a very hard decision. Remember, the child who would be a "perfect genetic combination" of you and your DH's characteristics could also be the perfect genetic combination of any negative traits you possess. For DH and me, that could have been a perfect genetic storm as we both have mental illness, substance abuse, and autoimmune problems in both our families.
That being said, I wish our kids looked more like me, so it's worth some effort to find a donor who will likely help you to have a child who looks like you and/or DH. But, plenty of kids don't bear much resemblance to their parents, so keep your eyes on the prize with a proven donor.
