I suggest you set up an SPF record i have set SPF records for my domains for a while now and i see no negative impact of any kind , the whole idea behind SPF records is to HELP you .
the comment by Marcel about creating the SPF record properly is obcourse a good idea.
you can refer to the following "Wizards" that assist you in creating your spf records based on the input you provide.
