I had a J94 for around a week before I ended up returning it.
Detail was really nice and I thought id got it running ok, then one day it ran badly and started to play dead. Sometimes it was ok, other times it wasn't so back it went.
Im tempted by a kernow 1361 and certainly tempted to try another J94 but worried about a repeat of last time
The J94 can still be got new from Hereford models in a few liveries including the ltd edition yellow
