It about the same as the Scuba Pro G500 series with a few less parts. Its a great reg for performance. Don’t know the price for the Aqualung Legend LX. If the price is about the same. I would tend to go for the ScubaPro S500, S555,S600 or S700 series instead. They are made better and also will have a better resale value when your done with it. But the Aqualung Legend LX is a great performer. You’ll be happy with it.
