Thanks guys. Thats helpful.
I have a circular saw and a couple of straightedge options so I can and probably use that for a while. That works easier for sheet stock but isn't really viable for, say, ripping 2x4 stock.
After I left Lowes, I went to Sears. Neither of these trips had any thing to do with saws, I was just "browsing".
Sears had several portable tabletop saws. I wouldn't have any interest in any of them - flimsy. I had a real good look at the DeWalt and it appeared solid with good features. I had never considered a saw of this type so I posted this question. I don't really need it to be portable, just small. My plan would be to make a dedicated cart (I made one for my spindle sander) with locking casters, etc and affix the saw to that. That way, I get a saw and storage.
Craigslist is a good idea.
Well, no hurry. Maybe I'll just get a big cabinet saw and tell my wife she has to park her car outside.
