Cheaper? Argh, I hate to be beaten on a bargain. Can I raise you a pair of leather breeks for £20 from Oxfam online? Or maybe I'll just accept defeat graciously.
Never mind, I just moved house and the old owner left the garage empty apart from, inexplicably... a jumbo can of silicon spray. I realise that with the new (soon to be squeaky) boots it must have been destiny!
Looks like I can get off my high horse on the service costs too - deffo a DIY job next time though.
