I heard that the hx were iffy also same as chemtex, I'd say that they are very easy to work on, they make one very much like a phoenix where it's all together with machine on water tanks and fuel tank all in one but has a 25 hp engine with a bigger blower, think it was $13k plus import tax 1.5% plus shipping £1000 plus vat plus any fitting charges so it's approx £12k inc.
