Your wants seem to mirror mine on features. I want a cast iron base, foot brake, pull out chip tray and the 2" spindle bore is nice too. The PM1340GT looks to be a very good machine but I want some features it doesn't have. I can't afford a PM1440GT so the PM1440GS fits the bill. I know Matt has sold around 100 of them but I can't find out much other than what the Manual and Matt say. The GS is a Chinese machine but Matt says "the build quality is good, but it is a Chinese machine."
Just to muddy the waters some there will be a cast iron base for the PM1236 out very soon, as in next week, and the new PM1236T will be out in June. The 1236 falls just short of my needs and the 1236T is close to the 1340GT in features so I am back to the PM1340GT or the PM1440GS.
Hopefully a PM1440GS owner will chime in. I had the same problem when I bought my PM1030V a couple of years back. There were 40/60 out but nobody was writing about them either.
