I was in a similar boat but refused to build my own system. Huginn was a perfect solution for me and I really enjoy using it. You can write your own agents if you need to but I haven't had to so far.

Since I set it up a few months ago I've been using it a bunch, it's event driven system is great for when you want to trigger off multiple streams half way through a flow. You can also go back through past events if you want which is really powerful.
