I can't say enough about the service and knowledge at weaknees. My Series 1 Tivo stopped dialing, so I ordered the modem kit, a new fan and a 160 gig hard drive, formatted.( I had tried some other options, like the PTV instant cake but my computer just wouldn't get it done. I tried all the correct positions, and jumpers but it was a P3 and something wouldn't work. I gave up and ordered the 160 from Weaknees.) It took about 30 seconds to drop in the replacement 160 gig. I kept the old 40 gig for a spare. The Tivo lit up and went right into a standard setup program. The new, standalone modem, dialed and worked properly. Unless you are a real hobbyist, you might consider the Weaknees option. It really doesn't cost that much.
