So who wants to see what I eventually went for??!!
None of the above suggestions unfortunately, and also totally different to what I was initially looking for!! I'm pretty sure I'm not the only one that has happened to!!

So, what did I get?
I picked up this modular tool chest from the local big chain hardware store, Bunnings.


As you can see, it also doubles as a handy amp stand


This particular chest has a top lockable compartment, and two separate, lockable drawers


The top section habdles a 10mtr/30' extension lead on a reel with four power outlets, plus an additional multi point power outlet, just in case. In the plastic bag, I have some CD's for sale. Plenty of room still in here


In the first drawer, you can see there are 7 compartments, with removable dividers. I have a bunch of random items in here including a spare tuner, spare strings, gaffer and electrical tape, a multi tool, and wire cutter, hook & loop cable ties, Microphone, pen, pencil and pad of paper, spare capo, and spare pics, and spare guitar strap.


For the moment, the bottom drawer only contains my guitar and mic leads, plus a small 3.5mm lead for plugging in my phone for additional tunes.
There is still plenty of room for my single pedal, and power cable for the amp




I will be getting a small collapsible trolley that will have straps to hold everything in place, including my guitar and mic stand.
I can further add to the chest my purchasing additional boxes which all lock together, as per the photo below.


Thanks to everyone for your suggestions, I hope all of the options has helped out someone else!
