The PMG's used on those machines are Chinese in origin (Ginlong) and appear sound in design terms, the alluninium blades are, as always open to personal preference, and probably open to comment here.
Has the TLG design been tested over a period of time? (maybe 5 years) in harsh conditions, that would be my first question before purchase.
Nothing against what he (Terry) is doing, he's certainly keen to help, thats the impression I get from across the pond.
