Camperic - where are you located? In the United States, you can do much better - and be a lot safer.
I'm guessing that you aren't in the United States - those meters that you listed aren't common (or available) in the United States.
You can buy a CoaguChek XS or a Coag-Sense meter for a range in prices from almost nothing to $700 or more. (You may be able to buy them and have them shipped Internationally - you'll probably be able to get strips shipped to you, too).
Test strips run $4 or $5 a strip.
I've seen Coag-Sense meters for a few hundred dollars (these are usually last generatiion, but still excellent meters). Recently, a liquidator has been selling strips for about $2 or so each. (I bought two bundles of 42 each, including transfer tubes, for less than $2 each - I tested them, checked with the manufacturer, and they're fine). I've also seen some offers at medical supply distributors that give you a meter if you buy a few boxes of strips. This is more strips than you can actually use before they expire, but you can probably sell a box or two and bring the actual cost way down.
Personally, I wouldn't consider any of the meters that you listed. The Roche CoaguChek XS, and the Coagusense Coag-Sense meters have much greater distribution, there are millions of CoaguChek XS units out there, and supplies are much less expensive, the meters are much easier to get, and supplies are much less expensive. I don't know the number of Coag-Sense meters in use (nowhere near the number of Coaguchek meters - but still a fairly substantial number.
The point is this -- you can get your own meter online or, perhaps, from a distributor. You can get strips on eBay. You shouldn't have to pay those ridiculous prices. One suggestion - whichever meter you buy, please test weekly (rather than every 10 days).
If you're able to, you may be able to self-manage. There are resources here that can help you with the management (although if you involve your doctor to take the results and adjust your dosage, you shouldn't have problems getting prescriptions for refills).
I looked at the RCS (Remote Cardiac Services) website -- they are showing the Hemosense meter being used. This meter has been discontinued, pulled from the market, because of test inaccuracies. You may be looking at old prices, or an old service.
