Hi Aaron,
Not sure if I am misreading your post , Do you mean lots of options for commercial work? or lots of options of equipment?
If equipment , then T/m is a must ,portys wont hack the larger jobs,,,,,,,,,, oh dear
seriously t/m will cope with most, a quality machine for agitation, ie. multiwash or rotowash is my choice , and as a large percentage of commercial are l/p I would suggest a decent machine for encapsulation, Cimex been my choice , others will do the job but an average buffer will not be as effective or time saving as a specialised encap machine.
Or you could go down the route of muck spreading with bonnets, has its place but very limited .
