For a good one not broken +mags&bayo with matching parts and in good condition.
A decent SVT will run about maybe $800, but don't expect to get too much extra in the way of magazines, bayonets, or anything else.
A bottom rung SVT goes for about $600. Think hard about this one, because any spare parts you might need later could very well cost you more than the gun itself.
I've wanted one of these for a while now. They're beautiful, historical, feel great in my hands, and seem to magically fit me with the stock and cheek weld.
