A bit more info on the canister:
"It's missing the intake tube. No media and may need a small section of 1/2 inch tubing replaced because it may leak from the tubing. I did a cheap fix on it and it was fine but I would still probably replace it. The canister itself doesn't leak. Has a new o-ring and impeller shaft and runs well."
Does dropping the $25 for it still seem like a good idea?
