This is going to be one of those how much you want to spend threads as you do get what you paid for.
Around 1991 when i started my apprenticeship my gran bought me my first box as a present for getting an apprenticeship. We used to get the MAC dealer come around and in 1991 she paid £365 for this box empty. I can not fault the paint, drawer slides door locks or anything it's over 20 years old now (where's that time gone) and other than needing a wipe over with a wet duster is in showroom or show van condition.
A few years ago i started running out of room in it and i iffed and ammed about trading it in with MAC or Snap-on for a roll cab or bigger box but then decided against it. I went to FWB who at the time were agents for TENG and i think they still are. They had this box discounted to about £100 with a free 1/4" socket set i thought ok, Teng aint bad stuff so i bought it and have regretted it ever since i do wish now i spent some more money and bought a better quality one. The whole build on this feels flimsy and not very strong the locks feel like if you gave the lid a good hard pull you would pull the lever of the barrrel and the drawers are roller free so they don't slide that freely or easily. Now only the cheaper lower quality kit i have live in that one as i just dont trust it for security. The Teng one is alot younger than my MAC box and is showing it age alot more than the MAC box
MAybe thats because i'm used to the quality of the other one as that was my first one, but the TENG box is with no shadow of a doubt seriously inferior to my MAC box. You need to decide how much you want to spend then you can cxompare some inthe same price range
In Work we spent Nearly £20,000 on new hand tools last year and the agent they went with were BETA. NOw some of the BETA tools we have are seriously overpriced junk and are very poor quality. We did however get 3 roll cabs and 1 static workshop box which was a huge roll cab with hug top box and 2 huge side boxes fitted. The roll cabs do seem to be holding up quite well as in work with 40 different people mistreating them they seen to be ok. All the tools chest and workshop boxes though have needed new locks fitted to them which was done under warranty
