In my experience the difference between cheap budget electric guitars and more expensive high quality guitars is more marginal than you think. There are many similarities and often what actually differentiates them is the actual labour, care & attention to detail and skills that have been invested in the more expensive instrument and conversely deprived from the budget instrument. The price of the cheap instrument is likely to be because these factors, which are the most labour intensive steps in an instruments production, are often shortcut or neglected allowing the manufacturer to sell in the budget price range. By allowing the budget instrument to receive these at a later stage we can vastly bring up the quality of the cheap budget electric guitars up to a point of comparability with the more expensive guitars. Of course there will be some difference that cannot be eliminated using this process such as quality of the hardware used but again there is an opportunity to change these things on a budget instrument at a later stage.
