options seem the way to go, page-10

If you must go the oppies beware that you may be looking at some big spreads, the liquidity is just OK nothing special. The problem with the oppies is that if the heads turn on you may be selling into a big spread to get out.

Its not really worth the hassles when the fully paids are so cheap themselves. I'd rather pay up and go the fully paids for a few more cents. Each to their own I like as much liquidity as I can get.
