One issue that could be important is there is no height adjustment for the handlebars this makes the bike fit more difficult and may make it unpleasant to ride depending on your height. It's not a bargain at £200 its about the going rate I would say for the spec.
Argos are a box shifter with little support.
Another option here;
It's heavier but does have height adjustable handlebars, slightly better rider weight capacity but apart from being a bit more stylish in my opinion especially if you go for the aluminium silver finish (steel bike just described as an aluminium finish paint job) is a lot cheaper.
