Hey randy, been there done that. Key is storage and anti theft. If you dont have a place to put your equip. Then enclosed is your only option. Theft is rampant in this industry. I lost a thousand dollars in equipment while i went into a wawa for a sandwich one day. Yup. Protect your hard earned money. Dont let someone walk away with it.
Next...a 54" rider/zturn is next. Go used and keep a few thousand of that money in liquid for the rainy days you will have. Protect your assets and keep some cash ready. Other than that....go to work and learn! Dont take any crap from the bigger guys, they all started where you are. Do good work and next year see what you dont need vs. What you know you need, o.k.
All the best. Stu.
