I'm in need of a table saw for my work.  My need is for residential cabinetry.  I work mostly with pine, mable, hickory, aspen, and MDF.  I have a "job site" saw I use during framing and with rough work.  I need precision/finesse with finish work.  I need portability to some degree.  I have job trailers with dove tails and full ramps for loading.  The cost point is important to me but I'm more concerned purchasing a saw that does the job.
I have convinced myself, through experience, I can work with a 30" rip fence limitation (right or left).  Again, I think precision is the most important to me.  I want a rip fence that is dead on accurate every time.....no movement, no slop, blondie (and blackie) hair size adjustments, no tape measure required to blade for setting.  I think I would prefer belt drive.  I say this partly for reducing the footprint, if required, of the saw when it is transported.  I do have a bad lower back, so its movement on casters (that lock) is important to me as well.  I normally setup in a garage area with cabinetry/trim work.  I would also like to get thoughts on the table itself.  I'm assuming I want cast iron for the best performance.
I've considered a Ridgid R4512.  It is a 13amp 10" saw with 30" right and 15" left.  Cast iron top.  Around $600.
I'd appreciate any thoughts/suggestions, or real life reviews, you may have.
