I have 2 MailFoundry 4100's for sale, they have full support until Jan 2011, and that can be transferred to the new owner. The units are 2 and 3 years old, still running ok, and the cover you take from Solinus covers hardware issues.
These units are currently located in a UK DataCentre in Manchester, I will ship @ cost anywhere on cleared funds (the payment mehtod is Bank Transfer only)
Local pickup would be best.
Asking price is 1800 GBP ea, if you want an invoice for them, then it will be Plus VAT within the UK, or a reasonable offer for both units together.
Any questions please PM, and I will try to answer you ASAP.
I would like to add I have them advertised elsewhere.
