Any ideas for a good item to invest in?

[Saint Crazy The Follower]

Seeing as my college classes start soon, I won't have much time to make money, so I wanna buy something so that the price will go up while I'm busy with other stuff.

What item(s) should I invest in? It's tougher than I thought to pick one, I don't wanna buy something I actually want, because I'd probably keep it. xD

Also, any other sellin' experience you'd like to share?

I bought some mith armor a while back at around twenty grand a pop. Last time I checked, they were selling for about fifty or fifty five a piece.

Evolving items are usually the best thing to invest in, and so are some of the rig items.

first gen. evolving items are the best to invest in. Most of them, once fully evolved, sell for very high. That's how I made most of my gold.
