I'm hoping for some help with finding a new sleeping bag. It's not for bushwalking per se (as in carrying it to do overnight hikes) but rather for regular camping (from where I do the bushwalking

I'm having some trouble as all the sleeping bags I have seen around in shops (like Bogong, Paddy Pallin etc. here in Melbourne) are the cocoon shaped ones.
What I'd like is:
- regular, old school rectangle shape
- not too expensive (some of the cocoon ones are $500+, that might be abit much for me!)
- no hood
- 2 can be zipped together to make a double sleeping bag
Also it doesn't have to be super warm, I don't plan on going to really cold climates like snow, and like I said, it doesn't have to be super lightweight or compact as it's not for overnight hiking but lighter/more compact is still good

Thanks so much for any ideas or suggestions if you know of any sleeping bags like what I'm after.
