Agreed.. as with ANY and ALL Tech Devices, the price will continue to fall until discontinued.. You just gotta decide when it is worthwhile for you to 'jump in'..
As with most things like this, I say Buy It if you think it helps, and then USE IT and be Happy!! ** If you wait there will always be a Better~Faster whatever it is, and may often be Cheaper too..
With my mid-2011 MBP I just upgraded to an aging Crucial 512GB M4 when it fell below $400.. I am VERY happy so far!! 😀
