Speaking of HF tools that don't suck, I really like their battery powered transfer pump, I use it for all sorts of transfer duties, from gasoline to diesel fuel to light gear oil and they are pretty cheap compared to the ones on Amazonian.
I see they are on sale right now for under 10 bucks. I tend to buy a couple at a time and they are hard on regular D cell batteries so what I did / do is I bought a couple 2 packs of Li-Ion rechargeable D cell batteries and I charge them (all 4) and 2 on the shelf when the 2 in the pump get weak, I exchange them with charged ones. Much cheaper than tossing conventional D cells. They do expire after a while but for under 10 bucks a shot, I don't care. In fact, I presently have 3 of them, one in use and 2 standby.
Nice thing about the rechargeable D cells is they hold their charge just fine sitting on the shelf, waiting to be used.
