If you're looking for a cheaper, faster, more flexible way to manage your projects, I have just the thing.
Manymoon is an online project management program which marries the data in your Google account with your business tasks, milestones, and documents.
You need to register to use Manymoon, but it's free -- and fast, since you can log in using your Google account information. The site is cleanly designed and easy to learn; you can create projects, generate milestones, and assign tasks. Not only can you leverage your Gmail contacts to assign resources to your projects, but you can display all the details on your Google Calendar.
You can use Manymoon for free, but you're limited to 5MB of document storage and a handful of restrictions, such as no more than 5 time tracking entries. $10/month takes away all the artificial limitations and gives you a comfortable 3GB of storage. (25GB is also available for $20/month.)
