I watched a few video reviews of that D11 2-3 weeks ago and the consensus was that it’s not particularly good, especially given the price. It certainly doesn’t do it for me.
Like others have said, plenty of bargains to be had, eg the Sian and Chiron are £250, the Defender is £110 for starters. However, I’ve been hoarding some sizeable builds throughout the year, awaiting a rainy day or two and really don’t need anymore. Then again… you can never have too much Lego.
