Acquiring the right equipment is a balancing act. You don't want to purchase equipment that has all the bells and whistles and at the same time you don't want to purchase equipment that will do a poor job and affect your production.
You need to purchase equipment that will do the right job for you in the start-up phases and continue to do the right job for at least a couple of years.
You may also want to see if leasing is available. When you lease your equipment, you get a 100% tax write-off compared to writing off just the depreciation. Check with your accountant regarding what's best for your situation.
Another option is to see if you can rent equipment. This is a benefit if you are just starting out and need access to top-of-the -line equipment, or if you're not sure which piece of equipment is best for you – by renting you'll be able to try out different brands before buying.
When you are looking for your equipment, make sure you shop around. By doing so, you'll find that sales people will give you tips, pointers and other ideas that you may not have considered. It's their business so they should have a good background regarding the marketplace.
The more you shop around and ask good questions the more knowledgeable you'll be about the equipment.
