I just bought a 2003 Suburban 2500 with a gauge cluster on its way out.
I was going to use this site;

That said, fixmygauges.com looks to be similarly priced so I'll be talking to them as well before I buy anything.
EDIT: I'll be using Carl at fixmygauges.com - leaving the other link for another option in case others find this thread.
