I would say, do-it-yourself.
If you do it yourself, your likely-hood of having more prospects is FAR BETTER than with any *guaranteed traffic* site. Personally....don't waste your money with those programs. & definitely don't get yourself into any SPAM conflicts. Not only are there fines involved with spamming, but you could also lose your affiliate status with GDI.

I say you are absolutely right. I have been on the net since prodigy was out for MS-DOS.. I know that if your not the very first to come up with something, or "have created your own business from scratch" - then forget it. You send out your link to all those search engines and get what? spam in return. You would have to spend 100's to all of those search engines just to even attempt to get a good listing on them. Personally, I can get 5 people better by sending them a personal letter than sending my 1 link to a thousand search engines.
