I had a quick look at the £40 50+10 rucksack and it seemed well made and well padded to my all be it inexperienced eye.

Looks like a very descent ruckack. Personnally, I'd have prefered 60 + 10 litre, as a 50 + 10 is smallish for backpacking in anything but very hot weather, but too large for Winter day trips.
I bought my 70 litre from Aldi a few years ago for £15 and it's has good service and has lasted. Minus points are it's too heavy and it has too many straps and zips.
Flippin' 'eck! Allow me to recommend http://tinyurl.com, who will happily turn the above nonsense into this:
The above nonsense is the standard way to define hyperlinks as defined by RFC 1738. If double clicking the link does not send you to the page then your browser is not compatible. Similarly if the link gets wrapped, which from your reply, appears not to be the case. I'm well aware of TinyURL and the like, but choose not to use them because there's a standard in place. Additionally, in future, when browsing the archive there's also the possibility of links being rendered useless if these 3rd party redirection services cease to operate.
