I used to use Priority Pass and found it very useful. Used to pay around £250 for unlimited visits a year and in my last 2 years paid around £150 a year which allowed 10 visits. I would say it depends on your travel needs and would strongly suggest researching it first. Priority Pass gives access to over 600 lounges worldwide and they can be found on the site. I no longer use it now, due to changes in flying requirements and current BAEC status. That said $60 sounds like good value if you can use it.
