I find the Vector/ Crosslink design very good at soaking up the small bumps, they seem quite active.
Seal & bearing kits are available on eBay, I bought some from a US seller last year.
I'd probably go for a set of the later Crosslinks (circa 97' on) as they have a slightly better design, a coil shock, and no integral stem.
They did them in different sizes of steerer, so don't get one from a small or Way Big frameset, a set from medium or large frame should fit a middle of the road sized frameset.
