There is a web site that contains free transcriptions of over 10,000 Revolutionary War Pension Applications. It contains about 10,500 pension application as well as many roster transcriptions, all from the Southern Campaign.
This can be a double edged sword: transcriptions can contain the errors of the transcriber, but they are certainly easier to read than the original documents. The ideal strategy would be to use the transcriptions to determine that you have an ancestor who made an application, and also to help you decipher the original documents when you ultimately get them.
Remember, these cover only those who fought in the Southern Campaign. Check it out at http://southerncampaign.org/pen/#m
