It sounds like your off to a good start. Yeah I would defiantly go with the duke traps they are good quality and affordable. Do you know what you want to use for lure/bait? I use tuna fish for coons it is very smelly and seems to work great. I use bacon grease for yotes, skunks, foxes and even porcupines. Bacon grease seems to be irressitable to the critters.

I also would HIGHLY reccomend these two websites I have learned alot from them and I buy most of my supplies and traps from them..... F&T trading post http://www.fntpost.com/Categories/Trapping/ And... PCS outdoors http://www.pcsoutdoors.com/
Good luck!
Warning: Trapping is very addictive.
