I just purchased an extended A/C hose from a company in Phoenix called AAPAK (1-800-832-5544 attn. Warren Willingham). They charged my $216. including UPS shipping but not yet deducting a $100 core charge. I ordered it Thursday AM and it was delivered Thursday PM (yesterday) one week later. The workmanship appears to be excellent and I can't beat a net of $116 around here. One of the leading local A/C shops in this area charged me $175 6 years ago to rebuild my standard hoses.
Editor's Note: I haven't ordered through this company, but I can say that I have had three good recomendations for AAPAK.
