STXL11002 on a TEC140 would work very nicely. I would not recommend a guide scope and use the self guiding filter wheel or use an OAG.
I use the SBIG STi guide camera and have no trouble getting guide stars.
I use a TEC180 and 110. The flatteners work very well with pinpoint stars to the corners.
The STXL has the advantage of an AO unit available and there was a thread about AO unit advantages elsewhere on this site. Even though the TEC140 is around 1000mm focal length I would consider an AO unit as well if you are going that route.
I would also get the Feathertouch focuser as you mention it is very good.
I get pinpoint stars to the corners of my TEC180 easily with a 16803 camera so 11002 which not as high will too.
I think it would be a good match.
Greg.
