There's nothing big or clever about having cheap gear, and equally there's nothing big or clever about having expensive gear either. Use what you can afford and/or need and just get on with the important job of playing the actual music.
I always put it into perspective by considering that when I was playing in a synth band in the 80s it would have been possible to buy a small mid-terrace house in need of modernisation for the same amount as we had spent on the musical equipment we took to gigs. In that respect taking £10k worth of instruments, effects and amplification on stage, when compared with property or even car prices these days, is peanuts.
