I use mine on the field frequently and for that I would recommend you an iMac bag such as this one (is the cheapest):

There are other bag companies selling their products at ridiculous prices but with this one (reasonably priced), there is no need to disassemble anything. Have a look at their video:

Other alternatives include hard-cases, although it is the most professional-looking, water-proof, shock-proof, high-tech option, still is expensive and large hard-cases are cumbersome to carry and even fit in your car's trunk... I use a lot of trunks, cases, and bags for on-location jobs.
