I never use the "at market" option.
I very rarely put an order in the market until I see the price I am after. I don't see any benefit to me in signalling my intentions to other buyers or sellers when I don't have to.
When I see the price I want I simply place an "at limit" order at the top price in the appropriate side of the market depth. This is effectively an "at market" order but without the risks of any consequences should there be a delay for whatever reason in my order being processed.
