Gentlemen ,first off let me point out that DIYMark is in Australia , so the dollar value is different. I have done research here in Australia , and the price he quotes is comparable to all other reputable trainers available here. To purchase from Tower he would have to add import duties and postage costs , making it dearer still. So Mark if you can get more details on what model it is , i feel you have a go there . So if modelling is in your mind for a new hobby , go for it, but remember it is addictive as well as being the best hobby in the world .
