For me, it's not even a question...? I get the BIPAD8 off of eBay on a regular basis.? They last forever... like, literally, forever.? I have three in my home and feed them from my DM16x16 DSP cards.? They are simple, work perfectly, and are a great product.? I have to note any contract I sell that they are (B) stock product, but I warranty them for a year myself, make excellent profit on them, and if it breaks (never happened with several dozen sold) it is inexpensive to replace.
Still miss the MX850/ML600 remote.? That one was killer as well.
