I am in the same boat as you finishing up my larger tanks right now and looking for a new inexpensive project. It's also nice to have an established tank you can plop a fish that's getting bullied while you re arrange your tank.
Anyways I think I'm going to go for a small planted tank as I have never tried live plants. But I'm still deciding. I'm also thinking about using it as. "grow" tank as my local fish store is awesome (shout out to fantastic fins in Livonia!) and gets in a ton of really rare stuff and I often make impulse buys so It would nice to have a tank to put them while they grow out and I can figure out where I want to put them later on.
Keep us posted on what you pick and how it turns out good luck!
