you could kill 2 birds with one stone.
get your wife a nice pro-quality
kitchen-aid, the 525 watt lists for about $425 but I bought the wife a reconditioned one (with full waranty) at an outlet mall for $249.
it has a PTO socket on it that will run a
meat grinder ($65), and you can get the
sausage making kit for another $15. plus they run a dozen or so other attachments.
it'll last forever, made of metal not plastic.
the big benifit is you spend 250-400 (depending on how lucky you are shopping) on the wife, making you the hero. and then only spend $65 on hunting. making you generous and possably deserving of spending some cash on yourself (like a new gun).
where if you where to spend the same money and just get a meat grinder to use hunting, that would be added to the mental list of money you spend on hunting instead of her.
btw- it's the wierdest thing, and I wouldn't believe it if I hadn't seen it many times with my own eyes. women will brag up these things as if it where something important like a new boat, gun, or video card.
