Posting this as I have bought one myself in the last couple of weeks, and personally think it is a bit of a bargain. RRP was £70, but has been reduced to £39.99 @ Comet.
This microwave was a Which Best Buy in their Feb report - they said "Excellent at automatic cooking, exceptional value. You can rely on this LG model to do a good job when you use its pre-set cooking and de-frosting programs. Uniquely among our solo Best Buys, the LG produces first class pasta when cooked using its specially pre-set program."
I have found it to be an excellent machine, cooking and heating well, with some nice extra features. It looks pretty smart too.
Price shown is for reserve and collect - delivery is an extra £5.95 - in which case this microwave would be cheaper @ Amazon, where it is £44.99 incl supersaver delivery. Even if the website shows no availability for reserve and collect near you, I was told that it is possible to order and pay in store, and have it delivered free to that store for collection.
