Yes, 5V wallwarts are nice!I have some 7.5V, 1000mA wallwarts for the times I want to use the barrel jack connector.
Not sure where I got them from tho, I don't see them at the site I expected.
A bit off topic, but I have had some success getting more unusual AC adaptors from surplus stores. For example, American Science & Surplus usually has a number of odd ball wall warts on offer.
