Hi, new to posting. Was surprisingly able to buy a r4511 at my local HD but havent picked it up yet, they had a total of 4 in stock ( now 3). I was all excited but then i happened to read a review in FWW on the r4510 - the portable. I m wondering if comparing the two is like apples and oranges. FWW made the 4510 seem like a reasonable choice ( not in comparison to the 4511). There are 2 primary reasons i m considering the 4510. One is the portability factor I do have limited space and being able to move it around might be helpful. The second is the set up - seems the 4511 is a major pain to set up ( not worse than any other stationary saw) whereas the 4510 is good to go out of the box. I m an amateur (very) woodworker. Are these two machines vastly different or just one s on wheels?. Please offer any thoughts. thanks!!
