Try and find a review of a Wiggys bag? You are joking aren't you? Ever heard of the Internet, or youtube? The reason he doesn't appear in magazines reviews is because he sells direct, and refuses to provide sample bags for review - if they want one the magazines have to buy one. And the specialist magazines have a habit of not being too "unkind" on heavy advertisers' products., and not reviewing kit they don't get for free, or advertising revenue from.
When you first mentioned Wiggys some time ago, I did try to find reviews, but all I found were people on forums. etc. There are some reviews, but they tend to be isolated, without context or comparison, and there is no mention of things like EN ratings (I know that its a lab test, but at least it gives some numbers). And although some reviews are very good, not all are. On Trailspace, for instance, there are two very much contrasting reviews:

The second review uses phrases like 'Fantasy temperature rating' and 'The inner bag was supposed to be warm down to -15°C or so: i froze my bottom of around 0°C.'. The chap complained about the loss of loft - apparently he wasn't impressed about the customer service. You can see how that sort of thing might put people off.
And these are all fairly 'unoffical' - no reviews from the likes of Backpacker Magazine, Outdoor Life, Field & Stream, Outdoors, etc. Yes, I know he doesn't sell in stores, nor sends out ads, test samples, etc, but I'd like something more than 'they are great' from his own website and so bloke on the web/Youtube, etc. The Superlight that you mentioned is $175, plus shipping. So thats £114 plus shipping and whatever Customs want to charge me - for a bag I have hardly seen any reviews for, and have never laid eyes on.
Yes, he sells loads to the US military, but is he really 'a huge competitor to MH and others in the US'. Who knows? I do know that TNF, MH, Kelty, Big Agnes, Marmot, Sea to Summit, Western Mountaineering, etc do sell well to the general public, but unless I see numbers, who can say? But if you dont advertise, and only have two shops and online, your distribution is likely to be a little limited.
If you like his bags, great. And its good to bring that brand to our attention, and if others like them too, thats fine. But for most of us, buying a bag is a bit of a shot in the dark at the best of times, because everybody is different. Buying a bag from a foreign country, from a bloke which even this sympathetic newspaper article points out writes 'online diatribes' and is 'bombastic'

And Johnnyboy1971 still doesn't have an answer to his question - but if its a 2-3 season bag, you can do well at the moment for less than £100.
