It's been four years since Lego's done an underwater theme, and the new parts that have come out in the time intervening really make a difference. I'm really excited about Aquaraiders, and so far I haven't seen a single set I don't like. This set in particular is a must-have. The lobster-thingy radiates a nice "creepy-bug vibe", and I like the use of the mini-Piraka spines.
The saving-of-money starts now.
