I just got a new Metcal WS-1 stand for my MX-500P. It was only a couple more dollars than the equivalent Thermaltronics. It took a few days to get the money from my stash into the bank to buy it and the funny thing was there were like 5 people watching it the entire time. I just can't understand that-why watch it if you're not going to buy it and if you're going to buy it, why watch it. I have snapped up stuff like that in the past. Their procrastination is my good fortune.
Regarding the people watching, perhaps:
Waiting on funds?
Undecided if they're going to buy at all?
Reminder of some sort (maybe in the form of an attached note)?
Waiting for more feedback for that particular seller?
Whatever the reason, placing it in their watched list makes it easier to find later.
Speaking of procrastination, now you're out of excuses on making a full, detailed comparison between the MX-500P and FX-951.
Seriously though, enjoy.
