My mate only has 2 or 3 sizes of die but then all he does is make custom roll cages for decent money so gets a decent return on it. Then get £1500 back a year later the first day you listed it on ebay. If you had a specific one time project like a tubular chassis for an off-road buggy you could probably cough up the £2k for the bender and the 2 only sizes of die you need. The problem for hobby use is really you want a full set of die sizes sat in the drawer ready to suit whatever you fancy making that weekend. One individual die is not really that expensive when you consider the material cost, time and tooling needed to make it. I design stuff the other way around by choosing a tube size that I know he has a die for and building the rest around it. That means you can design something and know it will come out to spec. When matched correctly there is no deforming of the tube and, possibly more importantly, a known centre line radius. Meaning you need one die for each size you want to bend. It's a cracking bit of kit but he only thing that makes it work so well is having the dies matched exactly to the size of tube. A mate of mine has the all singing hydraulic jd with the dro.
