HP 48G - what next?

[JSS]

Thank you so much BartDB and mfleming for replying.

Well, I can't accept Prime if it doesn't support RPL. Just don't want to start from scratch, spending too much time on programming and learning completely new practices. It is a pity since a new Prime G2 costs just around 130+ EUR while prices for a new 50G are considerably higher, up to 300 EUR. The price for a pre-owned 48GX, G+ and 50G in good condition seems to be around 100 - 200+ EUR. The GX memory is very expensive (if you can find any.)

50G has the memory card, USB interface and better display. But what about he keyboard quality, is it comparable w 48G?

Any significant speed difference (of RPL programs) between 48G and 50G? And can I transfer most RPL programs from 48G to 50G w/o excess work?

Thanks again.
