Uhh....the problem is the 39 ounces. At this price range, you are better off with North Face's Kilo Bag which is an extra $10 but it saves you 8oz and it packs a lot smaller.
Or you could get GoLite's Ultra 20 quilt which is rated the same as the Orion but it's under half the weight for only $40 more.
Really, there are tons of bags out there that weigh less, pack smaller and are just as warm, but they do generally cost more. If you're stuck around this price, get a used bag or a 600 FP down bag. Or perhaps you're really set on synthetic?
Here's a shameless plug, I have a North Face Kilo bag for sale...it's in great shape. Search the buy/sell forum for my thread on it if you're interested. I'd sell it for $110 USD shipped.
