To return or not to return...the saga of the blender continues.

So, the offspring broke my beloved $40 Ninja blender. My several-weeks search for a used same-model replacement has been fruitless. (Why would anyone giveaway such a great blender, right?) The Chefman $25 blender I found, which I think is by the same maker as my beloved blender, has new safety upgrades rendering my spare parts from the old blender useless. Do I:
1. Toss/giveaway and keep the $25 new blender because who knows if I'll ever be able to find one again.
2. Return the new blender and keep hoping I'll come across a used unit of an identical model to my old one.
A blender isn't that essential that I can't go without one for another month or two, but I am missing its use and the spare parts from the old one are taking up a lot of space.
