I have two 630's, and a 405, so I needed a Multiswitch. After some comparisons, I bought a Zinwell WB68 off e-Bay. It took a month to get here because of the postal strike, but the total price with shipping to BC was only $25. The unit is small enough that it ships in just a padded envelope. It was obviously used, but appeared in good shape physically. Installed today and it's working perfectly! I measured the signal strength & EBNO, before and after installation; the results were exactly the same, across the board. So far, I'm happy.
