My build totalled less than £1000 at full price from online suppliers I did grab a few bargains along the way I have spent under £800, I am currently using MDF Base 75mm thick top as an alternative to carrying almost half a ton of steel and cast iron upstairs (The base I designed my router for stored for later use). If materials brought cut to size from somewhere like Ali Warehouse or using Extrusion as many do there is little need for machining plenty of drilling and tapping, although a chop saw with fine tooth tungsten blade cuts aluminium reasonably well. Have been machining Aluminium as easy as on my converted Mini Mill as for the wiring and PC interface is quite simple plenty of documentation and help available in forums.
