Thanks to everyone who has posted a reply, most of the information has been very useful and as of today has produced two more units to add to my collection. Sorry it took a day to respond but I did spent most of today at Del Webb with my wife, she hurt her back picking up our son who is six months old. Got the call while I was at work so I have not had a chance to reply until now.
Ed, I am moving in the next two weeks and we will be North of Bell and just west of the 303 (Bell West Ranch I think), a sudden and unexpected move but the best thing is this house has a third car garage that has added power and is air conditioned, I would say I scored with this one. I had just started building the benchwork for my layout in my current home that would have taken up much of a two car garage so I will have to change the dimensions some what due to the move. Good thing is I had already planned on a two level layout which this new garage will have to fit due to the space. Also, thanks for the invite I would really like to get to a train show soon.
TrainNut: Thanks for the advice as well, I have dealt with them almost exclusivley out here and to date they have not let me down. I have had dealings in the past with other shops that leave something to be desired, I guess we all do at some point. I do agree that usually the best prices and deals are on the net. Most of my stock has come from the net via N-Scale supply, Caboose Hobbies ect. Nice pics of the layouts as well I will try to get some posted as soon as I can start construction of my layout.
Woodone: Thanks for the help as well, I checked with Caboose hobbies and they the SD70MAC in stock which is close but they have some variable diffrences from the SD70M.
Herc Driver: I will let you know how they turn out, the Rio Grande unit should be done pretty soon and the Western Pacific unit is coming after that. Both units will be sound equipped DCC units. I am going to add BLMA fans, lifting hooks and grab irons to the back of the units to detail them as much as possible. I would like for them to be center pieces of my layout which I hope to complete construction by December of this year. They have four units in stock right now, the Rio Grande, Western Pacific, Missouri Pacific and Southern Pacific and all of the units are done very well. I know that the only comparison in N Scale is the Overland Units but they are brass and no one currently has one to compare the two. I am not even sure if Tower 55 has released their HO versions yet. However the decals, paint and details are very clean with little or no visible defects. Mind you I am not a professional scratch builder or detailer but everything is where it should be with regard to the prototype.
