No collection is complete without the +2A and +2B.

Amstrad took over production of the 128k spectrum and fixed a great many bugs in the ROM, which was then released as the 128k +2. After that, they went after the god-awful hardware flaws in the 128k design, and fixed those - and released the result as the +2A and the +3. (Said fixes sadly render quite a few games unplayable on the +2A/+3, but they had to be done).

The +2A is a +3 with tape drive instead of floppy. If you attach a floppy to the +2A, it will behave identically to the +3. The +2B was a further refinement to the +2A.

So in short, although the +2 is the most compatible of the 128k spectrums, the +2B is the most mature and technically advanced design, whilst still retaining the internal tape deck. It's the only model that can utilise IDE hard disks via a cheap ROM/IDE-interface internal upgrade. All others require a nasty expansion port adapter.
