NCR Servers

Hello,

1. My company is interested on buying NCR Server S11 or S29. I will make an RFP but I cannot find an approximate price for these servers. If you have more information on the pricing of these servers in the market, I would appreciate it if you could let me know.
2. If you happen to know any other NCR Server models and their approximate price, I would be very pleased if you can inform me.

Thank you very much in advance
P.
