Durability
The fact that it weighs 83 pounds tells me that it's made out of cheaper materials. MDF has it's pros and cons, but does tend to absorb moisture and prone to scratches and dings. Hence, it is more likely to show signs of wear and tear over time. However, it's the material used even on some tables over $800, and has it's advantages over real wood.
The Luster Long finish is designed to provide resistance, which is a feature you wouldn't see on lower-priced tables.
Gameplay
The Newcastle weighs less than 100 lbs., which means it's a light table. This means that it's susceptible to movement, especially when play is more competitive.
It's not a full-sized table (56x30x36), but it's just a few inches smaller. Playing on a big table makes the game more fun and realistic.
The high-performance rod bushings are designed to make them smooth while turning. Some of the lesser expensive models, like the Playcraft Sport 48" Table, have rods that are a little rough and inconsistent.
The oversized leg levelers are just that, oversized, compared to lesser tables. This gives the table a little more stability while creating a level playing surface for both sides.
Aesthetics
The wood finish gives it an attractive, pricey appearance. When I first saw this table, I was surprised that it was priced under $500. It fits into many different kinds of room decors. The robo players add some professionalism to it. The levelers do stick out a little bit, but doesn't take away from the overall aesthetics in my opinion. The surface has a real smooth look.
Who's It For?
I would buy this table for beginners, teenagers, and adults. In general, it's suited for those who want an affordable table, but want a little more quality than the ones priced under $200. I don't know if it's sturdy enough for intermediate play, though it's big enough. Experienced players may want a table that is a little heavier.
