Metal work pays my mortgage, but not the style you are starting in.
But...
For general stuff, as above, get a tool from a car boot sale for pocket change that has survived the past 40 years, and you can be fairly certain its going to be last longer than any budget tool from machine mart / Axminister / etc
Facebook market place is full of people clearing out older peoples houses and flogging bundles of stuff. A couple of weeks ago i went along to pick up some draws for work and it was someone's son in law liquidising a life time of smiting tools. It wasn't my field of metal work, but so much stuff there that would have interested someone. They were carting it (literally trailer loads) to the scrappie, as they needed to get the house on the market, and had no real time.
Most of my mechanics tools are ether new or second hand but current, but id never buy something like a vice new, as you would spend a fortune for something half as good as something 1/2 of the price on the used market. Anvils are silly money second hand now, but new theyre insane.
Large tools are a case of keeping a good eye out, and being ready to drive and pick up. A trailer and an engine crane lets you buy things that a lot of people cant. Or failing that, just confidence that you can actually shift the item by hook or by crook and thinking up somthing quick on the fly.
But, yeah, small stuff - boot sales and fb market place are the way to setup for a fraction of the cost, and a multiple of the quality of machine mart etc.
(for clarity, i was using a clarke contractor tool a few hours ago, purchased from machine mart, but you pick and choose these things - id buy the same tool again without thought even when it brakes, as ive had good life out of it, but you wouldnt catch me in there buying their spanners for example)
