I have 3 sr's and they are fine machines, the 4 station drill is nice on the gang slide, they are a bit of a pain to set the live tools (big reach and don't slip on the wrench).. sturdy, accurate.. the major weakness is the XB axis, it's REALLY thermally active, keep the room temp consistant and keep the machine warm and it'll rock, but if you're room temp change a lot you can forget about splitting tenths. that being said, most machines have that problem when splitting tenths, just more so on the sub.. the parts door tends to be a bit messy, making some internal oil splash covers goes a long way here. you can use the Z live mill attachment and still get the sub to the other cross live tooling, which is impossible on my L's, a nice bonus.. get the 5 place option, gtting the live tools for the sub precludes the ability to use speeders back there. the pneumatic ejector optin has a short stroke and was pretty much useless to me, the stock springy thing works good, but can goober up parts if your not careful.
