I'm finding the Aldi Ferrex tools good value and they work well. Three years warranty. They have a recip saw at the moment for £30, the 20/40V battery about £30 and the charger £15. I believe the batteries are Samsung. You can of course use the battery and charger for the other tools in the range. They have in the range a chainsaw, drill, grinder, polisher and multitool plus some others. The 40V operation makes them very powerful and as the batteries are relatively cheap you can take more than one to a site and/or charge one while using the other.
