Mine were in the 4-500 range each shaft with all new Spicer components, the welding and balancing was less than $100 of that if I remember, this has been a few years though.
Whatever they cost now I bet they're competitive and I know you'll be satisfied with the parts.
You'll find Central Truck is a great resource for lots of your project. Well worth a trip just to see what they have and worth a call even for the odd stuff, they've usually got it or can get it. I've been going there for 6 or 7 years now, a really great place to deal with.
