*note, this is my take. I am not criticizing any previous posts*
Sounds to me like the Sun is a great bike given that one is not expecting premium quality at a discount price. At that price, something has to give. A compromise in "beauty of craftsmanship" seems entirely fair as long as it is still structurally sound. I'm glad they build and sell a bike like this.

If you want high quality, you're going to have to pay for it. Nothing wrong with that.
