I just did- I had 126 a month ago, now I've doubled it- it was all Comp USA had and they were the only ones that had any memory for Dell. I called around town.
Took the chip out, took it with me, & had them scan it for a replacement type. That was $45 bucks.
Figgured I'd invest that & see what happened (not too much).
The Linux'/library idea is a good one, tho.

There's too much graphics and ads plopped down on any site today, to let the older systems with less RAM handle any type of net surfing. Used to be, 64 megs was considered a FAST machine.
My first computer in '94 only had 8, out of the box.
Upped that to 32 before I got another.
