If the money was there and someone said they wanted to get a Gibson I would say go and buy one now, but since we are talking about finance here thats why I advised the copy (SH) + bkps.
I was not talking about buying something just to sell I was talking about saving for the Gibson and then when you have the £1400 or so in the bank and the copy to sell you can really determine if the Gibson is worth the difference. You will know what you gave up to have it.
Then there is no chance that 6 months down the line you are paying for something you dont want anymore.
