In the wonderful world of military modelling there are kits with huge numbers of fiddly parts, vague instructions, kits that are just wrong .... I would rate SEM just below Tamyia who lead the pack in terms of accuracy, quality and buildability, the kits are simple and easy to construct - the bending of wire being the only major difficulty I have ever noted. I am not by any means a accomplished or master kit builder.
As for time - well I don't have much for modelling and perhaps I should make more time for relaxation purposes. But in terms of RTR well I ordered the Eureka E wagons having kitbashed one from SEM parts and the AMK kit. The construction took about 5 months of intermittent work - the RTR E is still on the promised list now according to Ron, November this year - is it 4 years for the model? So much for the immediacy of the RTR model. Is there some other factor at work Auscision seem to be very good at generating excitement and promoting their models.
