Stay away from OCZ Vertex 2. I've got the 60GB and I credit it as my last OCZ purchase ever.
I also have a 160GB 7200rpm or 10000rpm drive (Velicoraptor) and can say that they're faster than a normal harddrive, but nowhere near as fast as a SSD. Get something like a 128GB SSD and a basic hard drive with enough GBs or TBs for all your media and data. That's what I'd do.
