Though the sets are expensive, costing between $30 and $120 each, they are really good value since Marcus plays with them everyday. We just can't underestimate or undervalue the educational and recreational value they offer. Nicholas is likely to play with them more too, so we are obliging Marcus' requests for new sets. Already, he has placed his sights on a few of the larger and more expensive sets, like the currently out-of-stock Mobile Crane. Doting papa has even searched all over Singapore and hunted down the only set available (at least that is the only set we can find) and rushed to pick it up. It is now discreetly sitting in the study, all wrapped up, as one of the surprises for Marcus when he turns 4.
