I have to admit with the 12" meade, anything greater than say about 1min and everything goes up the duff.
Just like everything it depends on what you are looking for, some people just do fix ups or make something up bob the bodger style, others make sure everything is perfect.
Like octane said, if you want to get nice tight stars, then go with all you can get your hands on. and to boot, if you have a nice wide field scope you can swap it over and image with the guide scope, and guide with the main scope. its upto you mate
