DMs - premade or homemade modules?

As much premade as I can. After college who has time to write all original stuff. Even running published material can take most of my freetime.

I've sworn off modules. I can never know them well enough to do them justice. (Or, more likely, I'm just too hard on myself.)

I do find modules to be a great source of inspiration, though.

I've also sworn off preparation. (Or rather, I do minimal preparation.) Not only do I not have a lot of time for preparation, but I'm not good at it anyway. I may not be great DM, but I don't think I'm any worse when winging it than when running a pre-prepared module.

Currently, I'm striving to let the players set their characters' own courses rather than trying to funnel them into a predetermined plot.

We run Spelljammer, and take jaunts betwixt Oerth, Toril and Krynn. The best of all worlds.

I'm mostly using modules at the moment, but completely wired into my homebrew campaign world - which means both major and minor changes to the purchased stuff.

To see what it looks like in practice - come and read my storyhour!
