I have a 17t I’ve grown rather fond of and would like to have a little brother to go with it at some point. Not too many DSG’s here in the states though.
I would quite like a 17T but I don't have the room for another machine and I'm not sure I could get one in my workshop anyway, I had to take the door and one of the stops off to get the 1307 to go in.
They aren't that common in the UK either now, a lot of our better machinery has been exported.
That one in the advert would make a great second op machine if you had the need for low volume manual production (which is practically nobody nowadays).
Personally I would always choose the longer bed versions of the 13, they are so big anyway for such a small swing that it doesn't feel like it's such a space consumer when you get 40" or 42" between centres, though I'm aware space constraints are normally much less of a concern in the USA.
They did the 1307's in 30", 40" and 50" between centres, the latter being very rare, but the 13-1's only in 30" or 42"
My 1307 by 40" from the face of my 3 jaw to the nose of the tailstock with it fully on the bed measures 45", so they are a little conservative with the dimensions.
Oh and the coolant tank in the base casting on those 13-1's is absolutely tiny, barely more than a gallon, you can run in empty easily before it finds its way back.
