Not sure if this is a local deal but my local Aldi had a few of these Workzone Titanium Li-ion circular saws reduced down to £35 which is a brilliant price.
The Titanium brand is aimed at semi professional use and is usually priced accordingly. I have a drill and impact driver and it hasn't let me down. Also 3 year guarantee. Also comes in a decent storage box
Copied the below text from UK Do-It-Yourself Forum and someone who bought it a while back....
Aldi had the above on sale last week @ £69:99. 150mm circular saw, parallel guide, 1 hour charger, 24 tooth TCT blade, decent carry case & one 18v 3 A/hr Li Ion battery. In the case was an offer leaflet for another battery @ £40, so I bought one which arrived in 3 days.https://www.aldi.co.uk/18v-li-ion-cordless-circular-saw/p/070928038696100
Apparently Workzone Titanium+ is Aldis premium range of power tools and AIUI are available all the time, not just offers. "Made" by Walter Werkzuerge Saltzburg GMBH, no indication of where it's actually made though. Very good instruction book in perfect English.
Not used in anger yet, but I'm very impressed with it so far. Cast alluminum base, decent quality rip fence and it has a nice 'heft' to it. Seems well made.
Batteries have an LED indicator showing charge level, charger has similar. No riving knife (a benefit IMO) safety trigger button & a laser (not much use to me).
150mm x 10mm blades seem to be easily available.
Time will tell, but so far I'm very impressed with it. £110 for an 18v saw & 2 x 3 A/hr Li Ion batteries is a pretty good deal IMO.
