Good advice offered above.
A common problem with many (most?) of the commercially-prepared checklists is that they offer too much detail (I don't really need all of the V speeds printed out, or separate checklists for normal, short field and soft field landings). See
this example. As a result, they are great references for a quick review before flying the aircraft (particularly helpful if you switch back and forth between different types, as many of us do), but they are not suitable for use
in the aircraft.
"Sure Check" makes a stripped-down "pocket version" that would be more suitable for airborne use (see
this example); and if price is no object, "Check Mate" also has an abbreviated "QuickMate" (see
example) that costs twice as much. However, as has already been suggested, there is a lot to be said for making up your own checklist that meets your individual needs and is custom-tailored to your airplane's equipment.
P.S. I agree with Miserlou: whatever you decide to do, stay away from those clumsy flip-type checklists.
