I don't know what's considered good quality in comparison to others, but for the price you pay, I would expect it to be TOP notch...
Price is not always an indicator of quality.
Example: I dive a Viking Extreame dry suit. They can sell as low as $900.00 In my opinion Viking is one of the best dry suit manufacturers in the business but most other dry suits (Whites, SSA, DUI) start at a much higher price. It does not make them a more durable and higher quality dry suit.
Just my opinion.
