I need to replace the original 3x (left) side of an original manufacturer pair of Shimano shifters.

the left shifter says "Shimano triple" on it and the bike is a specialised dolce with 3x7 gears.

I found an image of the same shifters on the internet (but it's the right side)
this image isn't my bike but an image I found.

so I want to replace the left shifter as it seems seized up.
job needs to be functional not pretty as it's a bike for my daughter at uni - fixing wife's old bike.

is it possible for me to use any 3x shifter with integrated brake with the original existing derailleur etc.

she might want to change the handlebars from racer to upright in which case I'd replace both shifters and replace with regular brake levers. in that case can I use any 3x7 leverz with the original Shimano derailleurs?

what are my cheapskate options?

thanks
