I have been buying Basik o-rings for years from MedCare Products. The last time I tried to order the 20cc syringes, they were out of the Basiks. They did, however, have another brand (don't remember the brand, I threw away the box) available. There are a couple of differences. Number one, the Basiks are sterile, individually packaged. The new ones I got are not. This is not an issue for me since I primarily use them for feeding. Number two, the writing (green instead of blue) seems to rub off a little quicker. They do work just as well as the Basiks. If I recall, a box of 50 20cc syringes runs around $15-20. I have also ordered most every other size but don't recollect the prices. They also include caps for the syringes, which makes it nice when traveling with them. I did just look at the website and they are still showing the Basik out-of-stock. However, I would guess they do still have the other brand though I haven't tried to order in quite a while. I can highly recommend MedCare after having ordered from them multiple times. And, their website is fun to look at too! http://www.medcareproducts.com/ Chris's Squirrels and More is also a good website, and I can also recommend them, as others here have also. I think Chris' prices may be a tad bit higher, but not a whole lot. We also order from Chris' quite a bit for wildlife rehab supplies. http://www.squirrelsandmore.com/ Katharine Florida [Posted in FML 6411]
