EchoSign is a quick and easy solution to getting documents signed electronically. I was able to use the trial version for over a year before I exceeded the monthly free limit. I gladly paid for the year of use. My contracts are typically very simple and require one signature. I did not spend long comparing or researching alternatives but trusted the Adobe name and have been very pleased and regularly recommend the service to other friends and clients. I like being able to quickly review contracts out for signature and scheduling follow up reminders too! Overall I've been very pleased.
