Tool Chest / Shelving

Hi all,

Does anyone have experience buying or fitting out a garage? I'm looking for a tool chest and workbench, preferabley all on rollers so I can move them in a couple of years.

Looking at BigDug, for example, they do "Garage" standard tool chests (and everything else) like this: https://www.bigdug.co.uk/bigdug-garage-24-6-drawer-tool-chest-rollcab-set/v/BDTCS61DBGR_1/

They also do "Trade"/"Trade+" tool chests like this: https://www.bigdug.co.uk/bigdug-modular-garage-5-drawer-roll-cabinet/v/TGRC1GB_1/

The Trade+ one is three times the price and 3/4 the size - What am I getting for my money that I don't get in the £100 one?
