This is what I use. It is not DIY but it isn't terribly expensive and it works great.

I too use a case similar to this. Keeps the tripod and a monopod thrown in for good measures clean, looking new and it quite easily transported.

May I suggest you read Atlas Shrugged by Ayn Rand? It is a wonderful book, and I doubt you could fully comprehend it. The problem with our world today is people such as yourself that think the only way to make a country grow is by expanding government and taking from those who actually produce.
I am only 14 and I know more about economics and politics than you, which is why I have made made $22,500 since 2009 on my own ventures. And please don't go about using the argument that if you don't agree with me, your stupid. Don't go on personal attacks in politics, or someone might go after you.

So are you saying you believe cameras such as Canon's
5D MK III and 1D X, or Nikon's D 800 do not utilize "advanced electronics", and should be considered "old school stuff" and sentimental technology?!?

No knowledgable, clear thinking individual could possibly make statements like that and hope to be taken seriously.

But to offer an answer to any reasonable portion of your question "Why Do You Drag Around Expensive Photo Gear?"... well a lot depends on what you shoot.

If you mainly shoot kids in the backyard, photos of your pets, vacation snaps, scenics, birthday parties and other similar situations, then a P&S will likely be fine for most of those.

If however you shoot action such as sports or wildlife (as I do) then a P&S is just not going to cut it.

Will your "advanced electronics" little Sony get these shots I've posted here?
Maybe, but probably not.

In any case since you have never posted *any* photos here you have taken recently, we have no way to know if you are any good and know what you are doing, and you are in no position to criticize other photographer's choice in gear.
