I have a Bosh portable that was about twice what you're looking to spend and it's just ok.
I've seen a couple of the cheaper saws on different projects and I'd have to classify them as "near useless".
Honestly, if you can't afford a decent table saw, don't bother buying one.
The power saw and rip fence is a good idea, but a quality saw and fence are going to set you back about as much as a table saw.
I have this one and really like it.
