i bought a 1 gallon brew kit at whole foods a while back. i now use the 1 gallon jug to harvest yeast. you could easily buy a little grain and hops and create your own recipes very easily. though, once i went all grain(3g stove biab and 5g "cheap n' easy") 1 gallon batches had no real interest for me since doing a 3g biab took the same amount of time and rendered a bit more beer. give it a try if midwest has 1 gallon kits!
