I'm a big fan of the Efile system. Yeah - the website is temperamental, but I bring my work home with me and file from my desk at the house. Is it worth it? Yeah, considering you save 9-12 months off the wait. When I manufacture, I file via fax. Solves that problem.
Sometimes it takes me a few days to get the forms filed, but what's 72 hours compared to the additional 300 days of waiting?
