It seemed the Metcal 500 family is about to obsolete, and the new 5000 fami= ly is=20 out. The MX-5010 looks very promise. After some research I also found there are "PS-900" and "MFR-2211" are new = too=20 and the PS-900 only cost half the price of MX-5010 (about US$650). The major difference I can see is the price and RF frequency, the MX-5010 i= s=20 using 13MHz, while the other two uses 450K Hz. I was wondering if anyone has tried any of those new machines and what do y= ou=20 think? There is even a dedicated PS-900 for solar panel manufacturing, isn't it=20 interesting? Funny N.
