This one's close to your price range (not my sale). Not sure if you'd consider it VG+, but unless you're willing to look at Player's Choice copies, it's the best I've seen at this price in a good while. Also, CIB vs just the box doesn't affect the value much as the cart & manual can be found in VG+ condition for $20-$30 pretty easily, while the boxes are fairly sought after and uncommon most copies were included as pack in games with the systems. https://www.ebay.com/itm/Super-Mario-World-Game-Box-Manual/193796462738
