I had a similar dilemma last year. I went with a used SCAG Tiger Cat with a 61 inch deck, Kohler motor with 90 hours. I paid 6k for it last December. I now do 2.5 access in about an hour. I was paying $200 per visit so I figured it'll take 3 years for it to pay for itself. And with proper maintenance it should last me 20 years easy.
