Well, considering that th MR sabers have long been sold out, there really is no chance of you getting one in a brick-and-mortar shop. You should probably just keep an eye out on ebay, here, or on other SW-focused forums like Rebelscum. And besides... Comic shops tend to sell replica props at the MSRP, so you'd be better off purchasing them online for a better price (or in this case, second-hand, for MR sabers).
