Is it just me or has anyone else noticed a marked decline in the quality of the M401 PT's lately? The last three I've gotten (from three different vendors) have all been marginal at best. I know this isn't something our regional suppliers can help, since they don't produce them, only resell them. Also, the latest one's are supposedly "improved". I don't know how being a foot shorter and having a green led makes them "improved", but I'm getting better hits from my batteries than my recent PT's. I suppose it's time to it's time to order some USB connectors, pull out the soldering gun and make my own.
