Plotter advice or for sale wanted please

[toolipz]

Hi Folks, Im after a new or used 24-28" plotter, very new to this business and dont have funds to waste by buying rubbish off ebay so if anyone could offer advice which ones I should be looking at from there I would be most grateful, If anyone has a spare or old one they arnt using any more I just want something to work on XP or Windows 7, Live merseyside but happy to collect or pay courier.
Im curently using a robo which is great but limiting to say the least for big jobs...

Hope anyone can help with advice ot other

Many thanks
J
