My TDS is about 130 in NW Calgary.
I have a 35 gal setup presently and just getting the tank up and running the first month of water changes cost me something like $80 in jugs of water.
Before you buy a single jug of water, go and buy an RO/DI system. The longer you wait, the more $ you'll waste on buying water. RO systems aren't that expensive and even a $300 system will pay for itself in a reasonable period (depending, of course, on your tank size / water needs).
I also use mine to replace the Culligan service I had so I'm saving even more. Add to that the convenience of not having to lug jugs to the store and it's a no-brainer.
