MSY cops a lot of shit, but for what they are, they're actually not that bad, if you want cheap prices, you're going to have to pay somehow, and if you decide to go to MSY, you'll be giving up customer service and quick queues for a little reduction in price. It's like choosing whether to fly JetStar or to fly QANTAS, for example.
For some people, such as myself, I really like MSY because it's pretty hassle-free, I don't really care about customer service, as long as I get my product and I'm paying less for it then I'm happy, I don't mind going on weekdays...etc. to skip the weekend queue either. But that's because I know exactly what I want.
Honestly though, you could always buy overseas, you generally skip over GST, which is like instant 10% off and on top of that base prices in the US are generally cheaper, of course there's always Warranty issues...etc. but I have never, ever, in my life have to deal with Warranty (and I own quite a fair bit of tech) - I will admit, on multiple occasions, I have had to open things up and use my soldering iron. So buying from the US might actually turn out pretty cheap.
