Smathersfish--Sounds like you are considering buying a new 97B with E work plus adjustable sight. That would be roughly a $1400 gun, I think, but you should check with CGW's web site to confirm. If I needed another one, I would buy it for nearly full list price. Or you can buy one yourself from CGW and get it with whatever options you want. I don't think you are going to find a B"E" at a big discount if its a new gun as described above.
I shoot a B"E" in bullseye matches just to irritate the 1911 fan boys. I shot a 9mm P-09 in 2014 matches before I got the B"E". I wanted more weight and bigger holes. The switch in early 2015 has worked out rather well.
