Any chance you have any reference costs for 100x50x4 and 50x50x4 mild steel box section? Will be buying in standard lengths and cutting it myself.
Yes don't underestimate these little things when attached to ballscrews. The mechanical advantage the screws give is massive, it will snap your arm like carrot and carry on like it never happened.!!

It's been while since bought any steel but last time I paid about £35 for 7.5mtr lengths 50x50x4. If you work on just less than double that for 100x50 you'll be close.
