I just ordered this off Amazon (and some gas cans) https://www.amazon.com/gp/product/B003XNPGFA
This is cheaper than the Gourmet version but I think it should be fine for my needs.
Thanks guys!
I'm a big fan of the isi brand, they are far more proud of them, but I think they're worth the money and you can get parts for them if needed (I've never needed parts in 15 years)
We had the smallest size for years, with the thought that one doesn't need that much whip cream... but have now since acquired both a pint and quart size, you don't need more than a pint imho , so quick and easy to make more if you need it, like 1 minute tops. And the quart one needs like 2 nitrous chargers. We also use the isi chargers they are a bit more expensive, but is not enough to argue about it imho.
Our quick recipe is one cup heavy whipping cream and 2 packets of splenda, and a squirt of vanilla bean extract. You could probably get away without the splenda, and there is a carb in each packet, but we like it.

We found the same vanilla locally in a smaller portion for less, but I'll probably buy this next time.
Stupid easy and good, so many things you can do with a whipper too, I've made chocolate malt whip cream that was amazing too... kalua flavored whip cream, really the list is endless.
On a side note, probably not a lot cheaper than rediwhip, but so much better tasting, and don't get me wrong I like rediwhip too!
