That is about the best price I have seen for that particular kit.

Another option would be the regular K-2006 kit from:
https://asp5.secure-shopping.com/spspools/

It is $49.00 and you could add on additional bottles of the chemicals you think you may consume more of in a season, also at great prices. (Cyan Acid, for example). That would probably get you the most bang for your buck.

The link to spspools was posted by someone else here, I ordered a kit from them and it was delivered 2 days later so they ship out fast.
