I'll simply repeat my opinion expressed earlier in this thread, that I'm not a fan of the BA bags that have no insulation on the bottom. I just don't like them, personally.
But, ignoring my personal preference in that regard, trying to be as objective as I can - I think paying $250 for a 49 oz, 30* sleeping bag can probably be improved upon.
Just one suggestion, here:

Same bag, except a closeout, different color and a long, but only $80:

From experience, I feel safe in saying that if you just keep your eyes open, you'll see this bag on sale for under $100 somewehere else before long.
I can vouch for this bag being truly only 40 oz. and truly an honest 20* bag as I bought one for my Son to use backpacking a couple of years ago and he has been loving on it for both backpacking and car camping trips since. I suspect the BA bag above would actually compress and store smaller than it is listed, but for sure this Kelty packs down quite a bit smaller than that.
Researching BP'ing equipment a couple of years ago, this bag came up consistently as the best bang for the buck out there in terms of warmth/weight/quality/price.
All that said, I just think it wouldn't be too hard to find a bag at least as good or better for your purposes than the BA for a lot less money. That is, without compromising to save a buck - truly at least as good if not better, for a lot less. I put the Kelty up just as one example because I'm familiar with it first hand.
