Rokenbok?
 

Anyone here know about the Rokenbok sets? (They are remote controlled construction vehicles & you can build like a huge city with them & such.) I am looking to buy a set or two to add on to the starter set for the hubby, and I don't know which sets would have the most "fun" stuff. I went to their website, but there are like 3239058029385 things to choose from!!

If you are familiar with Rokenbok, I would love to have your opinion on what to buy!
