The PX10 was Peugeot's top of the line 531 framed racing bike and in good original condition could sell for enough (they are most sought after) that you could get a fine start on another build.
The PX10 is not nearly as common as the UO8 which was their entry level road bike which sold for a fraction of the PX10's price.
It is nice that VO offers a french threaded cartridge bb and I know people who have bought them and are well pleased that there is now a solution to the French threaded bb issue... I want them to make a Raleigh threaded bottom bracket in 68 and 73 mm widths now.
