I own a RC K98 (bought from a CGN'er) in good shape with a decent bore. I paid $650 for it, but it did have things like the cleaning rod, front sight hood, and sling. Most of the RC K98's don't come with these little bits, so that ups the price to probably the $700-750 range. It shoots pretty well for a rifle that was captured on the Eastern Front in WWII.
If you can afford both, my suggestion would be to get both (as has been said by others). The only thing that turns me off of the VZ rifles is that straight bolt handle. I much prefer the turned down bolt handle (as that's what I grew up on, it just feels better to me when cycling the bolt from the shoulder) of the K98's. That said, aside from cosmetic things like proofmarks, the only real difference between the two is that bolt handle.
