Don't try PMD for anything construction equipment!
If you want a robust strong running, dirt working model, stay away from anything wedico! That pot metal cast aluminum is fast wearing crap that breaks easily.
Fumotec (Frank) has a WA500-6 wheel loader coming out later this year and if the quality/functionality/durabilty is anything like his dump trks, it will stomp the wedico 966 crap easily!
Frank works for Vario Helicopters, they produce and market his 80lbs excavator that he designed. I have this track hoe, it will dig hard ground! Frank will be busy with Spring trade shows, could be a little time delay with his replies, but he does write good english.
Deal direct with Frank, pay by bank wire, quality excellent, prices very reasonable.
And without a doubt, Scale Art is another great choice for fine quality, richly detailed, durable models and truck parts. Someday I hope to get a Caterpillar 963 track loader myself.
