Thanks for the answers.
There are a lot of very good news publishing systems out there, some of which have more or less exactly what I need. The problem is as always money, my site is a mere hobby, and already a money pit (not the least due to me not keeping it updated

).
The site runs mostly on ASP, and the news section is just one of many sections, but it is the first thing you'll see when you enter. To prevent having to change layout and styles too much I was hoping to find something that I could integrate without loosing the option to run the SSI file which contains my header that has logo and site menu, and maybe also have it in a frame with some sideframes with other content. There's too much that needs to be changed, fixed and updated already to have a news section which forces me to change the whole site too much.
This is the news section as it looks today. And as you see, it's not really very good, nor updated in ages. Wife, two kids and a house takes quite a bit of time to keep up with.
Come fall I might be able to cough up a few bucks to invest in something proper, but I still don't know what to get when that time may come.
