I agree with alexh. If that 2000 is mint, it will get a nice price on Ebay (take Red's advice and check that battery right now though). I had an Amiga 2000, then an A1200 and now I have an A4000T. I had a lot of fun with the A2000, but in all reality if I had a choice between a mint A2000 or a used A1200 I would take the A1200 and spend the difference on a 68030 CPU card (or better). You might even get a used A4000D from the proceeds of the sale of a mint A2000. The A4000 is a better machine all round than the A2000 and you will be able to get expansion cards much easier for it than the A2000.
If you want to upgrade that A2000 to its maximum capability you will spend $$$$$$
