We all seem to be missing a point here, I have looked at buying a Wills/Finecraft O2 for about 20 years now but given my modelling skills in metal modelling and painting I have been putting it off. On hearing that a RTR model was being produced I was over the moon but any model produced by Kernow will be many times better than what I could build at the moment faults and all.
The Hornby 4 vep had its faults but if they had not produced it we would still be hacking up mk1 coach bodies and grafting on ends to get something half way close.
While manufactures are willing to fund new RTR models and put the CAD drawings on this site to try and get them as close as possible we only have to look back 20- 30 years to see how much better our hobby is today in the quality of the models produced.
