Does anyone have any experience with these SPL meters? (Ebay #220082036106) Not necessarily from this source but these are the best pictures I could find.

Used 33-2050's don't seem that common and decent ones still cost upwards of $50 to get to me in Canada.

These ones look awfully similar (on the outside at least) to the older radio shacks. Would it even matter if it was deadly accurate, as long as it's consistent enough to level the speakers?

Thanks a bunch!

I haven't even seen this particular model before, but it does look very similar to the older RS meters - I'd be very surprised if it wasn't based on the RS meter. It'd probably be worth a shot if the alternative is $50 for an RS meter.
