I have an L47 and many attachments. I chose the model for its relatively compact size to FEL capacity over most AG models. (More on that in a minute).
When comparing the L47 and M62 models they are close in size yet I went with the L47 because it fits into my horse barn with raised breezeway...
If your business takes off make sure you consider transport ease. The 4060 with BH92 and L47 TLB are relatively easy machines to haul with a pickup. Anything bigger and heavier like the M62 might have you out of your comfort zone.
