Needed to replace my broken HL LaserJet 3600 as a matter of urgency, didn't want a new printer as had lots of supplies for my HPLJ3600. Athema supplied a HPLJ3800 very quickly which uses the same supplies and gave me a duplex model at no extra cost to the original price quoted. The printer is working brilliantly. So thanks for the very prompt service and the quality of the refurbished printer. David
