Possibly controversial, but I'd ran out of sets and there was nothing in Smyths I fancied that was within my "casual buy" price range, so just on a whim I picked up the Oxford Eiffel Tower. At €40 it's a mid price set compared to Lego but at close to 2,000 pieces I thought it was good value and would keep me busy
Yesterday evening and a few hours on and off during today and it was complete.
It's not a small set! The base is 4 20 stud x 20 stud plates and the whole thing ends up around 2' (61cm) tall (excluding the flag!)
Bricks feel similar to Lego and have an almost identical clutch, instructions were comprehensive and easy enough to follow.
Certainly good value and worth a try, unless you're a purist! :)
