I have the Halfords pro range in red. Top section with 4 or 5 drawers, middle section with the same (only bigger) and the big one at the bottom on wheels. I have had it for many years and it cost £250 for the lot (January sale). As yet there has never been a fault or rust spot. Nice quality unit with plenty storage. Ball bearings on the drawers and liners inside them.
Only thing I would say is DO NOT buy a cheap set, you will regret it. My mate has had his Snap-on chest for 35+ years in pro use, every day. He paid £800 back then, and has never regreted it. Mind you, he has it filled with over 40k worth of tools!!!
