I'll second Chaska's recommendation. Unicolor Print Drums (not the film drums) work great for 4x5 and 8x10 film development. My set was around $30 used. I use around 250ml of chemicals for my processing and haven't had any problems that I can attribute to this setup. (The one problem I did have was my own fault...I loaded both sheets of 4x5 into the same side of the chamber and they overlapped. Don't do this.)
