Extremely expensive, but it’s worth the price, it is very useful and is an absolute game changer. The only tip I have for getting this is (on Scorched Earth) is till get some oil rigs to get the oil, then kill Mantis on the dunes to get organic polymer so you don’t need to waste materials for polymer. Also for the cementing paste, a chemistry bench will be VERY handy for taking care of that. Hope this helps! ;)
