I believe the "troller" is $199. But I did a quick search and came up with a price range of $199-$400(depending on models).Everyone has a preference on their choice of electronics but with the spike in price of the showdown, would you consider an other unit? I think I saw them earlier this week at Cabelas for $349.
I would HIGHLY recommend a x67($269-299) before a showdown.
That's just my opinion
