after reading the forums i would like to add nec 3500 retail model along with my benq 1620. but i don't know where to buy it from? i am in us of a. anyone help me. also what firmware should i use with that, suppose i find a web site to buy it from?
Just get the 3520
3520 is oem and it got problems. 3500 is mature and i could use some firmware developed here. i need only retail version.
Go to OfficeMax and get one of these: http://club.cdfreaks.com/showthread.php?t=115930
The 3520 doesn't have any "problems" that you need to worry about, and it comes with software, so unless you can't live without a pretty box there's no difference.
where is the firmware for nec 3520?
It ran away over here.
