Yes, I believe the '62 has the link-pin set-up. I'm assuming you're looking for something with good street performance. I can only offer that a link-pin set-up is usually sought after by the off-road junkies. I've got a '61 Bug w/ a Baja set-up. The link-pin front suspension is known for being very durable in off-road applications. The design is such that it can take a whole lot of abuse (i.e., jumps) before failure.
I'm not sure if a ball-joint suspension results in a significant change in handling. It is a somewhat weaker configuration, but I don't think you'd be running a Sterling across the desert.
Adam is correct - there is a huge after-market for bug parts - and relatively inexpensive too. There's a lot of upgrades available including front disks, shock towers, etc. - so you shouldn't worry about that.
BTW - it wouldn't suprise me if there is a similiar internet forum (like SBW) for VW enthusiasts. Perhaps you can get lucky and find a site where you can get a more definative answer.
Good luck.
