If you want to buy a cheap case, then you are doing the same thing as carrying the amp around with no case. Spend the money and get a good case! Cheap cases don't take beatings to well. I worked for a production lighting and sound company for the past 13 years, I have seen a lot of cases get destroyed, just by getting knocked off the back of a truck. I'm not sure where you are located, but there are a lot of good case companies out there. In Chicago we used R&R cases, they are extremely well built and used buy a lot of major touring acts and companies. Just look at the construction of the cases, look for cases made from high ply Baltic birch or equally strong types of wood. Also looks at how they attach the hardware, I prefer riveted hardware, not stapled. And ALWAYS, get good casters for your cases, there is nothing worse then having to push as case with shitty casters. Also don't be afraid to ask the company what kind of guarantee the give as to what there cases can handle.
