I have the saw you linked, and, with a good sharpening and some additional set, it's a good saw. I'm lucky in that there's a local guy who does all the Forest Service saw work, and he does it for peanuts. I got him to give that saw a once-over, which cost 15 bucks and totally changed the saw (for the better). But, you're not going to do much cutting out-of-the-box with that saw. FWIW, I bought mine elsewhere for a tad less than that price (about 80-85 bucks). I like the saw --- in fact, I went out today and used it to buck some standing-dead aspen I chopped down. It was some work, but I got a full load in the truck!
I've also got a few longer old saws. Of course, they needed set/sharpened when I bought them, so just count on that part no matter which way you go.
One thing I'd add (or ask) is that you consider what kind of cutting you'll do with it. The saw you linked is sort of short. Sounds long if you've never used one, but 32 inches is barely a decent, full stroke. You'll pull the saw out of the log more than you want with that saw. 36 or 48 inches is better if you're going to be cutting any logs bigger than around 8 or 10 inches in diameter. At least, that's my experience. YMMV.
