Another big factor with the OLED deck is that it gets significantly more battery life. Especially in less demanding games, you can get 2x or even 3x the battery life of the LCD version (cries in LCD deck).

As for storage size, if you’re comfortable replacing the internal M.2 SSD, I believe you can save a bit of money there by buying the smallest size model (+ you get a bonus smaller SSD which can be nice for some projects). There is an ifixit guide for it.

If you’re not up for that and still want to save money, the micro SD card support is supposed to really good and practically indistinguishable from the internal SSD from what I’ve heard, but I haven’t yet tried it myself.
