It looks, the 8200 in particular, like very good value for money. I've not heard of the brand, so the frame is probably a generic Taiwanese design, but it doesn't mean there will be anything wrong with it, most frames are made in Taiwan. You probably don't need the suspension fork, it adds weight and it probably isn't a very good one at that price, but it isn't a deal breaker either way.
If you want a bike for all year round and need a rack I think it looks like a good find. It might be quite heavy and 30 miles could well be the limit of how far you would want to ride it, especially if you live somewhere hilly.
To get a similarly equipped bike from a 'name brand' you would have to spend at least £100 more. Just be aware that you are buying a skoda, not a mercedes. There will be some cost cutting somewhere - so try to buy it through a shop so you can look at one first and compare it side by side with a dawes, trek, specialized etc. so you can judge whether you want to pay more for a better quality bike.
Definitely get it built up by a good shop rather than mail order & self assembly. Make sure they check that the brakes are properly adjusted and stay adjusted, the wheels are straight and properly tensioned and that there is grease in the bearings.
If you can afford the extra and don't need rack and mudguards, or can buy them later when you have saved up more money, this kind of bike

will be a lot lighter and more fun to ride, especially for 30 miles or more. It is still good value and it is where I would rather put my money if I were you and could find it in my size.
