Recommended replacement drivers for Kappa 8

Selling some cabinets with original crossovers and was wondering which brand and ohm load i couldrecommend to a possible buyer that could be used to get as close to original as possible without breaking the bank.
Talk to Bill at Millersound, no one knows more about Infinity than he does except Arnie Nudell... Bill might be able to point in the right direction or sell you the drivers you need (not sure he sells drivers) but repairs Infinity as good as they get.
