Just Wondering

I was wondering if it might not be a good option for Accucraft to offer their engines in a "Custom tuned version"? When someone places their order they could take their chances on getting a good runner, or pay extra upfront and be assured that it would be. There are other products that are offered this way, why not Accucraft Loco's. If you are mechanically inclined and like to tinker you can take your chances with what is right of the assembly line, and if not up to par, get it running right yourself. If not, (Like me) it would be well worth the extra money charged to get a well tuned runner right out of the box. As it is now, if you have problems you spend a lot of time and shipping expense to and from Accucraft for warranty work, let alone the chances you take with the shippers messing up your prized Loco in route. I think many would be happy to pay more to get a good runner up front and avoid the hassles down the road. What do you think?
