4. Finally, how do you intend to finance it? An airless paint sprayer can cost under $200 or over $10,000. As with any equipment, you will want to buy the best model possible, so if you can afford $10,000, that's where you should look. On the other hand, taking on a debt in this economy should not be done lightly. If you are only able to finance around $1000, that will simplify your search considerably.
Keep in mind that many reconditioned sprayers are available at considerable discounts. If you already know the size or capabilities you need, then finding the right reconditioned unit will be easier.
Also keep in mind that machines can always be leased. While this may not be the most economical option, it may free up some cash flow for other important things - like payroll, for instance.
An equipment investment is the sign of a growing business. Investing in the wrong equipment, though, or in equipment you really can't afford, seldom helps anyone. Identifying your needs and your options before you talk with the sales representative will make this transaction smoother for everyone involved. Having done your homework, you will be able to go straight to what you want and communicate what you can pay. This should enable you to come back with the right airless paint sprayer for your business. Now go paint something!
