I use this one as well. Just got it a couple weeks ago, actually. I didn't get any calibration solution, but then again, I work in a Chemistry research lab, so I have access to Milli-Q water as well as stuff to make my own calibration solutions.
They come calibrated from the factory, but I never trust them. I read somewhere on this forum that a member's meter from the factory was over 50ppm off out of the box. If you are planning on being in the lower TDS range, you don't really need to get the 1000ppm calibration solution.
