$50 Fluid Extractor vs. $10 Siphon Pump?

[ZJ JIM 96]

I am thinking of getting some sort of device to assist in the changing of transmission fluid, coolant, and perhaps oil. I know there has been much talk of the fluid extractor that Bill D and others use, but I have not seen anything discussing the usefulness--or lack thereof--of the cheap siphon pumps available just about anywhere. Can anyone tell me why the more expensive apparatus is so much better?

just easier, insert hose in dipstick hole, pump a few times and walk away. No need to monitor or watch where the oil is going, no changing containers and easier to empty the large unit when done.

I paid 35 bucks for a 7 quart model from coastaltool.com or toolwharehouse.com

Best money I ever spent, I change more types of fluids more often and with less effort. My only regret is not getting one that pumps in reverse to empty the unit without tilting it.

I say if you can afford it go for it, it pays for itself many times over in a short timeframe

for transmissions I use a $12 drill pump from the hardware store

you be happier with the extractor..the cheapo pump doesnt work for much...the cheap pump you have to submerge the hose which gets it dirty..so you have to wipe it....and to fill a manual case you just end up making a mess..i use an oiler...spend the 50...everybody i know that has one swears by it...i wish i had listened..that is on my list of garage toys
