Thanks for all the replies and participation. I am still kicking it around in my head on which one to get. I am also debating on just making it myself. I have been reading up on what others have done, and it doesn't seem too difficult. For work, I am a design engineer. We have had projects in the past that I have had to learn and experiment with heat sealing. As a result, we have some hobby sealers, and two pretty heavy duty machines costing thousands. So, I have a good heat sealer that I can use, instead of an iron. What keeps me from jumping in is the cost of the raw materials. I can get the fabric from Seattle Fabrics and it will cost around $30 to $40 for 2 yards. If I get the down from thru hiker, it is $60 for 6 oz. So, about $100 for raw materials. The BA is $140 and the Warmlite is $155. Of course, making it myself will help me achieve my goal of having 100% of my kit made by myself, so there is that......
