Well I am glad for all of the responses, and I am also glad I have started a good discussion!
I can see the reasoning behind kegs remaining the property of the MegaSwill breweries, because at the end of the day they are worth a pretty penny (mmm Stainless Steel *drool*)
But at the end of the day, milk crates, being worth $3 or so, would very 'write-offable'
I am not in desperate need for any right now, but I thought having a few would be useful. Particularly as I am still scratching around in the dark world of bottling.
I will keep my eyes peeled and see what crops up.
Thanks all!
