Does anyone local (Vancouver) know if any LFS has calibration solution, as I'm sure I'll have to re-calibrate the darn thing after the battery change?

 <font size="2" face="Verdana, Helvetica, sans-serif">I bought a 3pak of calibration fluid with my TDS meter.  I'm sure it'll be a while before I use 1 let alone 2 paks.  I paid about $15 ($9.99 US) plus shipping.  If you don't find any cheaper, I'd be willing to sell a pack for $6 ($5 plus a buck to help with shipping cost).
