that is the point. It is easy to buy another 'toy'. It is tedious to practice using what you have. Thus many buy instrunents persuing sucess.

you need something to work with and despite great musicians sounding good on junk quality does sometimes sound better in ways you cannot compensate for. Also even if you can make cheap sound good it may be ergonomically harmful, or otherwise be a struggle. Thus it is sometimes justified to spend money on better.
