Mint Top Loading CD System+games, trade for a supergun or $225 shipped

I have a completely mint Jap Top Loading Neo Geo CD in box with manual, all bagies and packaging. I also have Samurai Shodown 1-4 and RPG all mint, complete with spine. And also AOF3 and Last Blade 1 also mint, complete with spine. I would really like to trade this for a high quality supergun that is completely compatible with a HNG64 Rev. 2, although I may sell all of it for around $225.
