I was pointed to this eBay listing but I think, on reflection, I'll confine myself to building this.

Although having a runnable gas turbine would be fun, I'd leave that to people with more time, space, and money than myself. What I'd like more realistically is a compressor disk or centrifugal impeller, as they're such wonderfully-shaped objects...

I've got a few small centrifugal impellers (some small Yank APU) that I use as candlesticks. They look great, but the labyrinth seals are also razor-sharp!
