If the finance part of it works for you, why not go for it? You never know the doors that could be opened. Maybe the vet's office needs to be brought up to speed tech-wise, and maybe he'd be willing to pay more if that is incorporated into your job - helping with the animals when necessary and doing the techy stuff when not. The animal medical field has to be huge, and involve much more than just being a vet-tech (not that there's anything wrong with being a vet tech!) and you might never know about what goes on behind the scenes until you're actually in the field.

Good luck!
