I have no connection to Levco, either. I've used a Monster (solder on version) for 4 - 5 months. My only problem has been that one of the power supply diodes blew. Luckily, our fixit guy could replace just the diode instead of the whole analog board. Symptoms: at first, the right edge of screen memory would accumulate white bits. Rebooting cured this. Then, as the disease progressed, random crashes started happening. Increasingly frequent until I called service. The chip clip is probably the best "clip-on" technology. It has bolts that tighten it around the chip, actually biting into the pins. I did notice on our several Prodigies (which I installed, not too much trouble) that as good as these clips are, they don't like to me inserted/removed more than once or twice. I had a problem with that, and when I called Levco, they gladly shipped me some spares. No problem. The greatest incompatibility problem I've seen is that General Computer's external Hyperdrive 20 will not work with Prodigies. GenCom's driver code doesn't run right. Apple HD20SC runs like a bat out of hell, though not as fast as on a Mac II. My suggestion: cast about to find a service guy at some dealership that REALLY knows the product. Then get what he can maintain. I personally feel that Levco offers much better product than Dove (due to some bad experiences), but if you are going to rely on a dealer to install or remove the upgrade, or even just to service it when it breaks, that that will swing things..............................bc ps. Remember that you can install the Levco or Dove upgrades yourself, but a dealer guarantees the installation. Might make it worth the extra $.
