IMO, you don't need a 0 degree bag, much less a -30 degree bag. You should be fine with a 15-20 degree bag (assuming a high quality sleeping pad). I will be taking a 30 degree quilt for CO first rifle. And, I would use the same quilt for 2nd-3rd rifle. Just with a high R-valued pad. I can always sleep in my puffy if it gets really cold.
For a "budget" sleeping bag, take a look at the North Face Cat's Meow 20. They can be found for around $150. It's a synthetic bag and a bit bulky. But, very solid for the price. Also, the Marmot Trestles 15 is a great bag in the $125ish range. I don't think I would go any cheaper than that.
If you really want a 0 degree budget-friendly bag, take a look at the Marmot Never Summer. Now you're in the $300 range. But, you are into down instead of synthetic.
Also, check the classifieds here on Rokslide. I've picked up some amazing deals on sleeping bags here. Best of luck in your search.
I’ve found the cats meow bag to actually be pretty decent. I used one on a short 5 day sheep hunt, a week long moose hunt and then a couple backpacking trips and while it’s not as roomy as my badger I slept comfortably. I’d reckon end one for anybody who needs a budget bag. I got mine in case I was going on trips with a really wet forecast and didn’t want to bring a down bag.
