@jiffydos:
I think that if you would like to add more ram to A3000 you are likely to spend a lot of money anyway. Accelerator may be the best option as far as features go.
- 16MB of ZIP ram...expensive.
- Simmfonie adapter...rare and expensive (usually it goes from $100 to $150USD on eBay).
- Accelerator card...probably the best option as far as what you get for your spent cash goes.
