I just realized my site4 has a 33" burn free monitor from 1999. What is the value of a monitor like this or does it matter to the value of the unit. Most have 25" monitors that i'm seeing on ebay.
if your talking the one in the showcase 33 cab as in this flyer, don't expect much interest.. I think most collectors avoid them due to the size of the cabinet. Maybe you will find some who likes fighting games who could use/want the monitor..
if its a hantrex polo 33, you can use the chassis on their 25" monitors. So you might get $150 for that alone.. Maybe if you know a local operator who runs those big cabs, he might be interested..
