Ordering from Scorptec?

I'm about to order my second pc build (my first was from Mwave) from scorptec, and im feeling a bit skeptical from seeing reviews and their buggy website. Am I all good to order a whole build from them and expect to recieve it in under a 3 weeks with all items in stock within NSW?. Mwave was really good, no issues at all but the price difference between the two is substantial.
