New horizon, slow motion work

Since where I work it is known that I'm into this "camera thing" I was asked a couple months ago to video and document the performance of our high speed bottling, labeling, and packing equipment for study in the event of equipment performance issues. They have a older video camera that does slow motion. But at only 4 second clips. It does a ok job. But, I'm sure they'll want better. So in the meantime to show what can be done I've used both my P900. And the older Sony camcorder. The P900 outshines the Sony in this in both quality and the P900 can do slow motion clips up to 8 minutes at a time. The clip from the P900 is much sharper and focused. So for the moment I had the company order a onboard led light and mounting bracket to go with the portable bracket that was purchased a month ago. So I'm starting to research a camera that meets the needs. And it needs to be portable. The whole kit needs to be easily transportable because it will be used at a corporate level at places from NY to CA. I'm looking for a smallish camera that can do slow motion videos down to at least 25-30 fps. Any ideas? The budget is flexible, but needs to be justified.
