Torn. I have a chance to buy an older BME102 from a friend. He put about 12 flights on it before sending it back to Kieth to be updated a few years ago. I don't know what updates he did. It has not been run since but I have no qualms about buying from the friend or the condition of the engine. I can get prop, mufflers, spinner and engine for a decent price. Or I can buy a new ZDZ100NG.
Two issues - power difference and the fact that I already have AMSOIL 2000 50:1 mixed for my ZDZ80 and wouldn't need a different mix for the BME.

Opinions?
