OK have been staying clear of the replies. Thats a lot of money for a RB of who knows what age and no support. Those are $25 value items you are taking all of the risks. And yes indeed you can get RBs for $25 a bit low in the lamp life. But do rejuvenate nicely. FRS class.
Brand new ones I think from SRS are that cost, consume a fraction of the power, great documentation, warranty, and modern control interfaces. What on earth would shipping and customs be?? Cute boat anchor though a real waste of anything.
