I've used HP calcs since 1973. I found the HP48SX and HP48GX to be very marginal due to slow execution times, *very* poor display contrast, terrible (especially low visual contrast) color schemes, irrationally expensive memory expansion options, inability to update firmware, etc. I found the HP42S to be far more useful (but it has the ugly brown/orange cosmetics of the HP48SX).
A couple of years ago, I bought a used HP49g+ for $20. I quickly found that the faults listed above were much improved on the HP49g+, though keyboard quality was poor. The built-in CAS is great. SD card support is a master-stroke, especially for installing firmware updates. The LCD is bright and crystal clear. Even the HP49g+ color scheme that many here have criticized has better legibility than that of the HP48SX and HP48GX.
I bought a new HP50g last year, with even better color scheme and much improved keyboard, though slightly poorer LCD. I'd prefer the ENTER key to be near the HP traditional location, except on the right side above the DIVISION key, but that's a minor issue to me.
I'm happy with the HP50g. I never thought I'd find a calculator I like as much as the legendary HP42S (but for different reasons). I never use any of my three HP48 units since getting the HP49g+ and HP50g.
