I've been waiting for a repair quote from 1st Texas and was going to call them since its been a week. Well UPS just dropped off my repaired F5, NO CHARGE. When I called to get my RA #, I informed them it was purchased used, and I realized there would be no warranty. Well they sent me a nice letter stating what was repaired and that there would be no charge for the service this one time. Many thanks to 1st Texas for great customer service.
