I'm looking for a reasonably priced ultrasound to check follicular growth in my ball python females. I ran across this ultrasound machine on e-bay for $999 with free shipping. I don't really know anything about ultrasound machines, will this one do the trick? Anything I should watch out for when buying an ultrasound? This is in my price range, not sure I want to spend much more, some of they go for over $5,000!
