Thanks Fred.
Prices being what they are, an eBay 604 1/2 ($280 - $350) plus a Hock/LN/LV replacement blade will cost more that the LN 4 1/2.
And then there's the LV 4 1/2 at $209. I've not heard anything about how these planes perform but if they're as good as the BU series of planes they should be quite good.
Anyone have one?
