where do you get new chargers and how much do they cost?

online, but they’re pricey (about $2 each), compared to buying an iSi soda siphon, which will cost you $35 to start but has cheap cartridges (about 80 cents each).
I cannot find anyone online who would just tell me it they’re interchangeable; they look like they should be, but I just can’t tell.
FYI, I CANNOT RECOMMEND THESE ENOUGH for anyone looking into making soda:
Homemade Soda
http://www.amazon.com/gp/product/1603427961/
fabulous basic recipes for both brewed, syrup sodas, and seltzers. The Grape Lavender is a favourite.
and
Fix the Pumps
http://www.amazon.com/Fix-Pumps-Darcy-S-ONeil/dp/0981175910
which is amazingly good history and recipe book of the history of soda fountains; it covers syrups, seltzers, mixed drinks, phosphates, SO MUCH.
Many of the ingredients will be available locally, but if you need some of the more obscure ones, I recommend The Boston Shaker, in Somerville, MA.

If you’re local, they’re amazing, but their online stuff is great, and they can sell you anything in store if you call them. They’ve had every single thing I’ve ever needed from Fix the Pumps.
(I used to bartend, and I get hired in the Boston community to make syrups for big events. If anyone around Boston went to a Bacardi event between 2010 and 2013, I probably made your simple syrup, pina colada mix, grenadine, etc.)
