It depends on a lot of factors. Are you using it for travel (some toys), or plan on holding your entire collection (will you outgrow its use if your collection grows, too)? Do you currently have a storage solution that needs replacing? Is $100 going to break your bank?
I invest a lot of money into my toys, so I am generally willing to pay the extra bucks to keep them clean, safe and happy.
I don't particularly like the look of the Devine playchest (I prefer the toiboxes), but I don't think the price is unreasonable for the amount of storage that it offers.
