I have sold a bunch of 74's and to tell the truth have only seen one factory caddy,all the rest were from China and they all .worked great. I had one minor problem when the small latch broke off on one,the seller offered to replace it but I went with a small refund as it still worked.
About 70% got Chinese batteries with no problems but one,a mk4 would not charge an aftermarket battery,pulled a used battery from a mk3 and switched them and they both worked.
There is an outfit on eBay selling 73,74's called play it again PC,they have hundreds of them dirt cheap. You can get a 74 up and running with some minor damage for less then $100.
2 CF-30Mk3's, 2 CF-71's, CF-L1, 3 CF-72's, CF-73, CF-74, CF-48, CF-50, CF-51Mk3, 2 CF-19's,7 CF-52's, FZ-A1 and other assorted beaters.
