[ICOM] Icom X75 Series questions

[flearl at msn.com]

Does anyone know the approximate production of the X75 series radios?  In terms of rarity, the 375 and 1275 should be the most rare, perhaps the 275 and 475 the most common, don't know where the 575 fits.  Obviously the PBT is on the older versions, also older logos.  I own a 275H and 475H, well pleased with them. I may want to add a 575 at some point, anyone have comments on that rig?
