The Howie Glatter solution is dead simple and when used makes it easy to see from the adjusting end of the scope.
The Catseye gear is top notch and very accurate.
The Orion (or similar) collimating eyepiece is simple, has no moving parts and requires no batteries.
Have used them all successfully. All have merits...
Currently in a Howie Glatter solution cycle...
Can not go wrong with any of them...if you do go the laser route make sure it is a high quality one.
