Porta-bands are a great option, especially with something like a swag table. I have an old old porter cable with a homemade stand and table, and although the cutting capacity is quite a bit smaller than the newer deep throat porta-bands you can get now days, I'm not sure there's ever been anything I couldn't figure out how to profile out on it (knife related that is).
All that said, I did pick up a used vertical/horizontal Wellsaw that also gets a lot of use. It came with a table that bolts on in the vertical position and gives a lot of extra "elbow room" than the portaband. I still use the portaband for quick little jobs, but the Wellsaw handles all the larger stuff, and it's really nice to be able to cut various materials to length by just clamping them in the horizontal position and walking away while the saw does the work.
The Harbor Freight vertical/horizontal isn't a terrible option, although I paid about the same (actually a little less) for my Wellsaw as what a new HF saw currently costs. You do get a little more cutting capacity, longer blades, and the horizontal capabilities with a vertical/horizonal. It may take up a little more shop space, but you can roll it around easy enough. Maybe take a look at Craigslist, and I see used saws of various brands for $250 or less quite often.
