Get this one, as it it also features stereo speakers:
1. 1084S-D1 stereo speakers, RGB 9 pin D/Comp $65.00
How ever, $65.00 might be a bit much, as I bought the same one in 2001 (well condition) for around 50$.
As for the rest, they should do the job too, but ask if they have stereo speakers. (I doubt it)
Othewise connect the AMIGA or CD-32 directly to another external sound output (Stereo amplifier speakers)
3. 1084 RGB 9 pin D/Comp $55.00
4. Amiga 1084 RGB 9 pin D/Comp $55.00
5. 1902A RGB 8&5 round/Comp $50.00
P.S.
By the way I just noticed that your original query, was posted almost 5 years ago!! I remember recommending you all that cool AMIGA hardware while I was having long work brakes at my previous job (changed 2 jobs since) Lol!! Nice bringing up old memories!
How are you? I hope you're well and kicking!
So what AMIGA did you get after all and what is your opinion of the good ol' AMIGA now that you have it?
