The build quality of vintage Aria Pro IIs is amazing. Elsewhere on this forum, you'll find the Aria Pro II club thread(s), and eventually, others will chime in that know WAY more than I.
I'm not sure what the going rate for Aria Pros is where you are, but unless that bass is in immaculate condition, the price may be a little high. And also, it's a medium scale bass, 2 inches shorter than the typical Fender-type bass. Some hate that, some love it (me).
