Yeah you can buy the panels, maby £500-£600 would have bought the lot. The way i did it the material cost was just a few quid for mig wire, flap discs and isopone etc, not that saving money was the main reason, infact the extra labour cost likley excedeed that so not worthwhile paying someone else to turn a sink into a bonnett.
I enjoy making things especially out of recycled materials(as you can seee from my other threads), using pre-existing shapes etc and matching them to what is required. More satisfaction creating something fom nothing than there is from punching your credit card numb
