I am a new user. I signed up on 6/30, the last day Infusionsoft offered the program with the fee.
When July rolled around, I too was 'upset' (Ask Jeremy, he'll tell you I was more than 'Upset')
I asked for my money back and was going to go with Aweber or 1ShoppingCart or something (I was livid!). I was fortunate enough to speak with Garrett Miles on the phone for 2 hours where he offered my money back. During that time, he did a good job of 1)explaining the difference between the two programs and 2) convincing me that overall, Infusionsoft is a good, honest company to do business with.
I then read the TOA and exactly what came with the non-fee new Infusionsoft model. (And this is just the basic, not the deluxe or Pro, so we are talking a $2000 fee, not $5000 fee)
Forget the affiliate option and the fact that Infusionsoft needed to spend more time with new customers a year ago because the software was less intuitive. You can even forget the 25,000 limit (one I hope to break and talk Garrett into letting me go over without charging me extra, Lol.)The on-going support that is available to the 'grandfathered users' that is NOT available to new users that join without a fee is well worth $2000 or even $5000 alone.
I don't know if I am letting a cat out of a bag, but I have spent some time in the 2X area that has 4 modules up and 4 on the way,( Scott has done a real good job there), and found the 1st module ONLY to be worth thousands in information. Sure, if you have been IMing for a long time you might not find the information as valuable as I have; but I have purchased a lot of information on internet marketing and it's various aspects, (IE: Adwords, Autoresponders, copy, SEO, even off-line advertising and I am in 3 other forums where I pay up to $100 a month to be in), and if Infusionsoft wanted to, they could take those eight modules and break them up and sell them either in pieces or 4 day seminars, add on a pay member site and make a lot more than they are now(don't get any ideas, Garrett). If you are 'grandfathered' and not taking advantage of the '2X' area (or were not told about it and now Infusionsoft is mad at me

) you ought to ask for access. (Not the guarantee necessarily, but the course/information). It would probably cost nothing for Infusionsoft to grant grandfathered accounts access AND might help increase the activity level there with input from marketers that have been at this longer AND there just might end up being enough information that you can use there to make up for a fee that was paid 1-2 years ago.
After long and hard thought, and having been given the choice between the 2 programs, I paid the fee. Now, I might just be an idiot, (I can assure you I am not), but so far, if I got no other benefit, the information I have already digested in the 2X area has been worth the extra money.
