I figured this info might be of use to someone looking for an inexpensive 4 channel scope. It isn't the X-E model of course so take that into consideration but at $325.58 down from $399.00 via Amazon Prime it appears to be the lowest price I have seen. It is shipped and sold by Amazon so at least you have some assurance it is what they say it is.
If you want to chance a returned model they have some as low as $292-$300 via Amazon Warehouse.
