Nobody is going to ask Rick Wakeman if one of his keyboards is a 'wise investment'. That's only a consideration if you really can't comfortably afford it; therefore, it's more a case of how much discretionary income/money you've got. If it doesn't impact you financially, then who cares how much it costs. JMO.
