Hey now... I use BME and with great results. They are light, powerful and great running engines however you will pay for for them. The price has tons do deal with supply and demand. We demand them so we are willing to pay for it. How many BME engines you see in the for sale forums? When you do see one how long does it take before it's gone. Product speaks for itself and doesn't need people like myself trying to explain why they are so popular and expensive. Add in the fact that Keith is a great guy as well right there answering the phone and your question what more could one ask for... a great product and great support but if you feel the price is too much then go buy a Zenoah and float you boat that way.
