Like Bell states, the fence is the most critical aspect of a "good" saw. Older Craftsman models lacked in that regard. Also, many 8" saws won't accept dado blades - they have a shorter shaft that won't allow them. The 10" Ryobi table saw (you don't show a link) - requires it's own brand of dado blade for that reason.

The benchtop styles may not be quite large enough for your purposes. I'd recommend Delta or Rigid brands for the contractor style (with legs). If space is not an issue and you intend to continue using the saw, the Dewalt saw is a very nice saw for that money - if it's in your budget.
