Definitely worth the $30 if you enter a lot of sweeps. I have been using Sweepstakes Plus for about 8 months, and it's so convenient to be able to create your own folders and divide up your Sweeps in the way that works for you. I've found it a huge time saver, and as we all know: 'more sweeps in less time = more wins!' Go for it, it's definitely worth the money. Also, these are good hard-working people here at SA, who deserve our support.
For example, they could have chosen the greedy path and given the paying section access to a larger data base than the free section, the way some site do. Instead they chose the honorable path, with the same data base for all and just pay for more features if you want to.
