A 55# bow is overkill for whitetail, as is a 30-.06...we can make a serviceable bow out of a hickory limb and a string from sinew; arrows from river cane and stone points. We don't "need" fiberglass and carbon and HMPE, we just like it.
Just putting it in perspective...
For the money part, if I remember correctly I spent less on my used Bitzenburgers than I did on the other jigs I bought new...and I still use them, along with several friends who borrow them pretty regularly.
Obviously any good jig will do the job. If you aren't picky, go with the cheapest one. If you are picky, try borrowing a few different ones and see what you like.
