Erm, I sorry I don't think it has.
To say that a newly introduced loco has a proven track record prior to It being available to the general public is premature and misleading. It appears that the loco has so far only been generally available to a small number of people having attended an invitation only launch.
I have no reason to disbelieve the positive comments this loco has received but all of those comments up to date seem to have come from people that were invited to attend the launch.
Although the purchase price of £160.00 has been mentioned a few times throughout this thread, I am so far not aware of any official price announcement so I am left wondering if those that have commented on the loco bought the loco at recommended retail price or discount. Perhaps you could confirm the expected cost? Also as too remove any hint of bias, perhaps you could tell us what input, if any and for how long you have had into the project.
Having read through Mr Suttons communication I applaud his philosophy and ethos behind the Locos introduction and note his quoted comments about listening too and accepting constructive criticism so wonder why others have taken it upon themselves (particularly in other forums) to disapprove of such constructive comments?
Once the folk that have bought the locomotive independently and I'm sure there will be many, have commented perhaps then will be the time to start talking about "Proven Track Record". (I'm sure you didn't need to pun)
Re your point about three separate threads for different aspects of the model, why not just stick to one thread to discuss the SLW Sulzer two? That way there can be no confusion as to what specific manufacturer, specific DCC/DCC sound system, specific type of loco, specific version of loco, etc., etc. is being addressed.
Finally let me say I just make the above comments/queries in the spirit of being constructive and wish the venture well. I'll have three please.
