Personally, I find SPF pretty much useless. Yes, you can use it to score some mail, but implementation is not very widespread, so you either have to go hard-core and reject, or accept the mail anyway, in which case, why bother?
There are some other issues with SPF that suck as well, including stomping on existing record types. Personally, I use greylisting and dspam, and my spam problem is pretty much gone. With mailing lists, I get about 2200 messages a day, obviously most are ignored, but I file 'em for archives, and was getting 300-400 spam/day. Greylisting took it to about 10-12, dspam by itself was 3-4, both together, I'm thinking I haven't seen a spam get through for several days, and so far it's been a long time since seeing a False positive... Do some more reading on SPF, and don't expect much.
