This has probably been discussed a million times
In looking into all grain I'm looking for a cooler to do batch sparging (a la Denny).
Right now it looks like my options would be between a Coleman Xtreme or an Igloo Marine (both rectangular) and was wondering if there are any issues with one or the other (for me the Igloo would be cheaper).
I'm also wondering about the size. If I plan on doing 5 gallon batches, maybe even some "big beers" (high gravity) in the future, what would be good a good size to look at, so that I'm not kicking myself for either having too much head space to not be able to easily keep a steady temp, but to not worry about having too small a size to deal with bigger grain bills.
