Not all providers are equal - things to consider:

Some are brokers that have little or no inventory and offer no installation, repair or maintenance services. Others offer the same services as the Manufacturer Authorized Distributors such as one-year warranties, repairs and technical support. Several companies in the secondary market even have capability to perform component level repair on circuit cards and telephones.

Consider the advantages

· Cost savings - save up to 70% over new
· Late model equipment at enormous savings - equipment often hits the secondary market soon after production
· Savings on upgrades and trade-ins
· Access to a vast array of technical knowledge - in-house technicians and technical support often available
· Equipment must measure up to "like new" specs - often equipment performs better than new because manufacturer defects have been identified and remedied.
· Warranties - Many offer a one-year warranty on all equipment.
· In-house repairs - companies refurbishing the equipment they sell often offer in-house repairs with warranties of up to one year on repairs.
