The answer to your question is conditional to the situation. If you're at the mall or Costco on a shopping trip with the family or helping a friend move, your answer will be different than most other times. But, most other times, a drawer system is worth it. I went from a DIY to a fairly high end ARB system and unless you have exceptional fab skills, don't waste your time and money on a DIY setup. Also, if you do a DIY system, avoid wood. Wood is fine for stationary type environments, but with the constant vibration in a mobile environment, with out using a buttload of glue, wood seems to come apart and be reduced to sawdust. High end systems are designed for vibration exposure and mine is still as tight today, as it was when installed over 10 yrs ago.
Almost embarrassed to show my DIY attempt that worked fine for a while using under the bed storage containers and plywood:

Finally graduated to the ARB "Outback" drawer system for my 80 series:
