Is Hosting a Garrys Mod Server Even Worth It?

I'm in them midst of setting up one right now all by myself. Let me tell you, with all the work I've been doing the past 3 months, it's all been server dedicated work. However, I've only been able to dedicate my weekends to server coding / troubleshooting and web design I do 7 days a week. It was so much work at the beginning, that it made me want to quit so many times. Also, having to pay $20+ a month for my host, isn't too nice when you aren't even making money yet!

All and all, the work really does pay off. Just put in the time, and watch your hard work grow into something awesome.
