i have a sp101 357 magnum i've had about 6 months, its still unfired in the case and i'm wanting to get into muzzleloading. i took it to my local shop and they had a new cva accura and a new knight vision, the owner said he would trade the accura and $50.00 cash or $75.00 trade for my sp, he said he would trade the vision and $75.00 cash or $100 trade for my sp. how good of a deal is this?, i don't know about muzzleloaders very much. the cva is blue and made in spain, the knight is blue and made in USA, the owner says he has a new stainless accura in storage if i want it, the trade would be the ss accura and $25.00 in trade. is this a good trade?,and are these good guns? should i look for other brands? thank you for any help you can give
