I actually had a Brillelli on order and waited three months for them to finally tell me they were going out of business. I live in Kentucky so elevation is not an issue that is why I am worried the 50cc might be too much. I think the Saito may be a little shy on power for 3d'ing but I will give it a look. So far it looks like the DA 50 is the way to go. Let me know what you decide ro347!
