I can take pics of mine later. But it fits everything you really need.

You can fit 6 of these in the bottom, but I only have 4 in mine. Leaves room for solder iron and stand along with some wire and other things.

I know you said hard case but I've historically done a lot of on site jobs (not necessarily pinball) and I can't live without my custom leather craft bag.

It might as well be hard sided. It's my mobile toolbox for many years now. It goes to pin shows, etc...

Fifty pockets! Impressive, although I'd lose tools/parts INSIDE a bag like that...

This tool bag has served me well for 3+ years now. It has wheels and collapsing handle too so I don't have to carry it everywhere. Has lots of pockets and large open space inside. It is made well and has been very durable.

Haha, it can happen. There may have been a few long job days where I just tossed drill bits and screws inside the middle compartment, then regretted that the next morning.

Here is a decent video that shows more about this bag.

Yes, these are all great options! Thanks to those who posted.

The best tool bag in the business is Veto Pro Pac, they're a little pricey but worth it because of the durability.

I would guess it depends on the tool assortment. And if it is tools only or repair/shop parts too.

Are you wanting a little case for some screwdrivers, wrenches, specialty tools, flashlight, maybe small meter, etc?

Or are we looking to include EVERYTHING up to rework solder stations etc.

I have a few of these little cases I love. Have meters in one with the padding, one with basic tools, crimpers, etc., one with some common parts (rubbers,balls,etc).

I think harbor freight has something like this too, but I never checked them out.

I like that these have some padding,dividers, and some pockets etc.

Ive been working as a tech at shows for the last three or so years. One thing I have learned is a tool belt comes in very handy. 90% of the service I do at shows is just with a simple nut driver and a pair of pliers.

Picked this bag up last night for just this purpose, they had several sizes...

That is a nice tool bag!
