Multi family coin op laundry Qs

[Brendan Reilly]

I have an old set of whirlpool coin op laundry machines at my recently purchased multi family.  based on the model number they are from around 1991 and the washer has had its second issue with the coin slide that renders the whole machine useless(the actual coin slot itself broke from the slide and I had to rig it to work last time since I can’t seem to find parts).

So now I have a dilemma with more variables than just an inop washer.

The washer/dryer prices are currently 1.25 and 1.50 since I purchased the place (can’t find additional coin slots ) and even if I found them the slots max out at 2.00 a machine (which appears low based on local laundromat prices). 

Do I

1. Keep working to find a fix(maybe another coin slide variety will fit?) to salvage these old machines from 1991?

2. Cut my loss on the washer, get a new one and use the working washer coin slots to bump up the dryer price until it breaks and warrants replacement? 

3. Cut them both loose and replace with newer machines?
