test kit recommendations?

I'm looking for a new test kit to measure pH & Alkalinity, Ammonia and Nitrite & Nitrate.

It looks like Seachem & API have what I'm looking for. Any recommendations between the two?

Thanks!

IMO it's49/51 in favor of API.

It's cheaper on Amazon for the API test kit. I would go with that.

Thanks for the recommendations!

kalelhawj - I live in Canada so shipping from Amazon USA is problematic.

I prefer API: http://www.igopro-online.com/API-Mas...t-p/labapi.htm and I ship to Canada.
