My $0.02

Go find the cheapest (Cabela's - Riverbottom or Backyard buck - brand made by Delta) 3D target with an equally cheap replacement vital. Each year I replace the vital once & I'm good to go. I also put mutlitple spots on the vital so I can shoot 3 arrows @ a time.

2nd best - Morell's (I think) Humungo (sp?). Made for broadheads and cheap. Bought one last year & I'll probably get a 2nd season out of it - only thing is my BH's are coming out the other side so in some cases (with both solutions) I'm unscrewing the head to pull the arrow.

A final suggestion (dad does this) - the cheap wal-mart foam deal (it's tough stuff & about 2" thick) on a round bale of straw - again - his BH's go through the foam but we're not burying it to the fletchings so we're not hurting the arrows.

Good luck
