Fair point Dave. The only thing is that you have to weigh up the cost against the amount of use you will get out of a tool.
I bought the smaller Wedge Block and use it all the time. Well worth the cost as it is very versatile. I would like a lot of the other tools but in all conscience I can't justify the cost against the amount of use I would get out of them in normal circumstances. If thy were cheaper then I might well buy them on the basis that 'it looks as if it could come in useful at some point'. Instead I tend to buy inferior but much cheaper products which meet my occasional needs. I suppose if my model output was more prolific things might be a bit different.
I find most things will yield to blunt butchery with a blade followed by applcations of various grades of abrasive paper... Finesse was never my modelling forte. (and filler remedies many errors).
