I recently purchased an HP Color LaserJet 2550 Fuser from Lake Erie Systems. It was a little pricey, but it arrived quickly and functioned as promised. Apparently I was not particularly observant when I purchased a new fuser because I did not see that they also had an exchange program for refurbished fusers. I inquired via email as to options to return my old (empty) fuser and possibly receive some sort of credit. The representative that I worked with explained that credit is only available for refurbished fusers but that he would refund me $10 regardless. I informed him that I had not received a shipping label to return the current fuser. He apologized and sent out a shipping label, which arrived promptly. I mailed the fuser back and received my $10 credit.
Bottom line: Lake Erie Systems delivers their products promptly and as advertised. Their customer service is attentive and accommodating.
