I was in your same boat. I started out with a back pack blower, line trimmer, a push mower and a 48 inch mower all packed into the back of my truck. I bought shindaiwa, e-mark and snapper equipment. The dealer was able to let me finance the equipmet. This has helped me over time. With new equipment you have less of a chance of a brake down. I hope this helps.
Also look in the search area, this is were I got all my advice. There is some great information out there for a lot of great people.
