Cut above the rest with magnetic board and handy large shelf. My 2 & 4 year old boys have used it every day since Christmas (so top idea for boys' mark-making) and not damaged or broken yet! Bit pricey (higher now than before Christmas) but design and quality definitely a good investment.
[2 years later] It's still in one piece!! Incredibly sturdy, both sides very well used for chalk, dry-wipes markers, paper-drawing AND magnets, so would still strongly recommend this as a good investment. BUT do keep an eye on the price; seems to vary quite a bit from week-to-week.
