From personal experience with the Record bandsaw which I had some of the parts were made from an very bad quality cast aluminum like the top and bottom guide carriers which just fell to pieces
I have been using a Record BS350 for about 8 years and it works great. There was a problem with the tensioning mechanism about 4 years ago, where it wore away the threaded rod, but Record supplied a complete new mechanism ( I was expecting just the threaded part) and it's worked perfectly since then. I resaw 5" planks, and occasionally cut veneer (almost) thicknesses (1.5mm) of 4" deep timber, without any problems. Like most tools, it is down to the care taken setting them up and using them that determines if they work well or not. And of course not using cheap blades, which are most definitely a false economy.
By the way, I have just read this back and am amused by my mixture of imperial and metric measurements. Sorry about that, but I use whatever system is easiest.
