We are in the process of putting an Aloha POS system together for a pizza restaurant. We have everything except for the server. Can someone please give us a suggestion on what type of server to look for? Used or New? Manufacturer? Model? Our dealer recommended to purchase a server directly from them, but it's almost $1500 and claims that their server will be the most efficient for the system (I think it's made by Radiant). Thanks a ton!
