Yeah - ICT Direct have no problems with just one or two machines. They were going to send me just one PC out for my headteacher for home use last week, but the order may become bigger due to potential interest from staff.
However, whether they can get you a LAPTOP with 1GB RAM is another story (their equipment being second hand) but giving them a call should sort that out. They might take an older model and manually upgrade the RAM in it?
When Ric said "ICT Direct can get you ANYTHING", I tend to believe it. If I had a choice, I'd go up there and take a look in person at what stock they have, however it's too far away :(.
