Owning the tool for $100, (I think mine was $85) is well worth the freedom to do what you want when you want and these tools make perfect crimps or I wouldn't recommend it here to another user.
Having to deal with going to a shop is timely and costly period.

I wonder how much having all those crimps done at a shop, even of perfect the first time out, will cost? Will it get close enough to the cost of the tool, not even taking your time into account, to make it worthwhile to just buy the tool, even of only for one job?
I mean we are talking at least 6 crimps? More if you run rear AC too.
