I buy the sawzalls 2 at a time when they hit $15 with coupon. I’m rough on them though so if they can last 6 months with me, they’d last a lifetime with nearly anyone else.
Many people dismiss HF tools but their Pittsburgh line is guarunteed for life and they’ve never given me any hassle about replacement on a single item ever. Also, some of their junk knockoff tools are decent too, as long as you accept that they are cheap tools. I bought a set of the flex head stubby ratchets and I use a pipe on them for breaking bolts loose. They still ended up lasting for a few years so I got another set.
