I had the same £300 quoted by Eastman but they also recommended Bryson! Their website looks like they know what they're doing but from the above feedback it's sounds a little disappointing. ELC much like Ken says, said that re-lining and new knits is like making a new jacket but for £300 there's a chance of picking up something on the dreaded eBay!!
They were pretty good on their communication, emailing me and ringing me to talk about stuff. The moulton they picked is gorgeous. I think they were/ are overloaded and somehow the jacket got returned incomplete by mistake. However the turnaround was several months.. I'll check, but including sending it back could of been 2-3, maybe more!
