As I said in my other reply I do love the 48K for it's size and history, but I much prefer the +2A/B +3 models, as they have the RGB port and I use an RGB to scart lead, my daily driver is this 2+A, I cut the tape deck off and put a divMMC inside, for instant loading, I first saw a cut down machine on a few years back and I just had to build my own, this one has the NMI and Reset buttons on the side with a Kempston Joystick port and a push to release SD card, the SD card extension was acrually a pain to make I had to cut open an SD to Micro-SD card adapter and solder some old floppy cable to the pins, I did try the SD card extension leads, but they were too long and the signal didn't travel, (it did on a smart card, but not with a divMMC)
Anyway, just thought you might like to see my machine as a fellow speccy enthusiast
