Having looked around a bit, I settled on SFI. I liked SFI for a number of reasons:
1. It is TOTALLY free.
2. The support on their website is excellent (especially for a blogger like myself).
3. It doesn't require any purchases, or anything I wouldn't want to do.
4. It can be managed online with a small amount of time.
Signing up for the SFI account was super easy. If you'd like to play along with me, you can do so by using this link.
Once on the site, there is a simple to-do list that, if you follow it, will get you enough points to qualify for Executive Affiliate status quickly.
I opted for the quick choice of buying a single (non-recurring) co-op unit, which qualified me within 1 hour and ALSO gave me 4 co-op affiliates instantly (that's right, no work, no waiting). It cost about $20, which I think of as a gamble - but we'll see how well it worked.
