Cheap fermenter for 5 gal batch

[Todes]

When I bought my starter kit it came with a 5 gal bucket. I want to do 5 gal Batches, I see there is the 6 gal bucket and the 7 gal bucket, but the bigger one is out of stuck . What do you think of the 6 gal bucket?

are you plan on putting in 5.5 or 6 gallons in to compensate for trub, yeast loss?
Also look around im sure theres a 6.5 or 7 gallon bucket on the web somewhere in stock
