We were/are an i-series dealer and picked up the Aspire when it first came out because of the short comings of the i-series..maily the ugly phones. We have found, that YES the Aspire is better in alot of ways to the i-series it also lacks in some serious ways as well. We used to be strictly Tadiran but saw that we could NOT compete with other companies selling cheaper phone systems. Some people will not but into longevity and keeping a switch forever. You just have to be VERY candid with people when you sell these systems.
