LA series is fine
Ninefingers,
I agree with your post, all except the part about the engine for a trainer. I think it would be better to spend the $50 difference between the FX and the LA on getting a computer radio. I have both the 40 LA (on my trainer) and an FX (on my GP Tracer). The LA has never let me down, and it has taught me a lot about the basics of engine tuning and care. Though the FX is a great engine, I think it really not a necessary expense for a trainer.
