Where is the pain? In your toes or in your balls? Is it a fitting issue? I go by if it doesn't feel like your favourite pair of slippers in the shop then don't buy. I don't go for the "you will wear them in in time bol locks"
I had a basic cross trainer too. It did a good job for training arms and legs but also got the heart rate up higher than running so good for cv training. It could be a bit creaky and noisy but that might not be an issue in the garage. Make sure it you can change the resistance and read the reviews.
Cheaper alternative is get a turbo trainer, if you have a bike.
Not the boardgame advert but the opening line to a song. Google doesn't seem to help. But what song open with the line "You sank my battleship". I know the tune, it's very punchy start to a song. Maybe a theme tune. But what is it?
