I owned a BME 90 purchased from Keith. Well made. Had a 1/4-32 Falkon ignition. They take a while to break-in but are reliable and well made. They will not make the power of a ST90 on glow fuel as originally claimed.

Back when they first hit the market, RCExl ignitions were, if I remember correctly $17.00 each if purchased in lots of twenty. There is a healthy markup on those bad daddys.
