Aerial Yoga Equipment Question

I'm looking into purchasing equipment so I can practice aerial yoga at home. Anyone have any recommendations? The OmniGym looks awesome and I like the idea of being able to practice outside in the sunshine but it is a little pricey. I can't seem to find much information on rigs to hang from the ceiling in the house. I've looked at the poles silks too but I'm not sure I could do aerial yoga with those- it seems like I would bang into my pole... buy maybe I'm wrong... Any feedback is much appreciated : )
