I must admit to having a real weakness for Makita now, the B&Ds, deWalts Etc I've had have all failed me sooner rather than later so now when I replace I stick with what I trust. I was pleasantly surprised when I found on my Jigsaw "Made in England" the rest seem to be made in the parent country, Japan.
After a good while of buying tools you realise that most manufacturer makes full on pro use tools (often with larger amp hour capacity batteries and all metal 1/2" chucks) as well as a DIY range* with (with cordlesses) 1.5 amp hour batteries and 3/8ths" chucks with plastic outer sleeves, and often advertised on the front page of the Screwfix catalogue. Buy the DIY range stuff and they don't last anything as long as the full on pro gear. No single manufacturer produces the best of gear across the entire range.
Pretty much the best jigsaw blades I get to use are Bosch Progressors.
*Some manufacturers that don't seem to do a cheapo DIY range and stick to very high end (read, Expensive) are Festool, Mafell and Hilti.
