The $100,000 was for freezing equipment, not collection equipment
A well-equipped fresh/cooled collection lab can cost approximately $10,000, but for freezing, its a lot more pricy. Of course, there are cheaper ways, but they are not appropriate for the quality required of international shipping.
For example, you can freeze the easiest type of extender (every stallion "prefers" a different type of semen extender, each of which has a slightly different freezing protocol) in a styrofoam box on a floating rack you built yourself, for approximately $200. However, the variability and imprecision of the method doesn't lend itself to quality contract work. The alternative is a $40,000 cell freezer. So it adds up quickly to build a lab that is of the quality you would want to send your stallion to.
On top of that, a lot of precision instruments must be used to measure very precise amounts. A set of pipetters can cost $1000. Centrifuge, which is optional in cooled semen, is mandatory for frozen, and costs $4000 new. A motility monitor/microscope in a high end lab (like those that freeze) can cost upwards of $40,000. When I added up the costs for the lab I was going to build, it was easily over $100,000US.
If you have access to a facility that freezes semen for $100/collection, you have a STEAL. In the US, $150 is average for a collection alone, plus the freezing fee which can run upwards of $450 for a domestic ejaculate. The semen extender ALONE costs $20/15ml which is enough for 30 straws, or less than four doses. Its not uncommon for the extender to cost the lab upwards of $100 per collection for a full sized stallion, and that is included in the total fee (ie, they don't charge extra if you use more extender).
You can learn to collect and cool semen in a short one week course (I highly recommend the Colorado State University short course, when they offer it again), and you can certainly learn how to do frozen semen in a day if you are a quick learner, but the skills necessary to do a really good job take a long time to develop. Tricks to working with difficult horses take years to learn and implement. I was freezing semen in a few months after I started working on my master's, but it was a year or two before I got the skills needed to do truly quality work.
Freezing semen to the exacting standards required by breeders is a difficult task. It isn't something anyone can just "decide" to do one day. It takes a looong time to build the clientel needed to pay for the expensive equipment and learning curve. You don't practice on client animals, and its expensive to practice on your own animals!
Also, in Europe things are a LOT different. Europe is FAR, FAR, FAR more frozen-friendly than the US is. It is NORMAL for a mare owner to breed with frozen semen, here in the US, its almost unheard of. Companies like Select Breeders are pushing very hard to educate owners and make it more affordable for the average owner, but its still out of reach for most normal people and average horses.
Also, quarentine is not required in the US for shipping cooled semen, it is only required when preparing frozen semen for export to a certain group of countries which mandate it. Its not a US requirement, its the import country's requirements we must satisfy.
