I picked up a really nice SE/30 last week and got it up and running. Honestly, it didn't take much, as it was in great shape.

I bought it from the original owner (bought new in 1990) for $40 shipped. Seemed like a fair price.

It has 8mb of RAM and the original 40MB hard drive. The speaker volume seems a little weak, so I'll have to look into that, but otherwise, it's really clean.
