Where are you located? Places that salt the road in the winter are no fun for coil-overs. If they don't salt though, it is nice to be able to raise it up a little for the winter.

I'd lean more towards the Konis unless you are going to have tire clearance issues. You should get more miles out of the Konis before you need to rebuild. Konis have been around forever and they aren't going anywhere.

Best option IMO is to buy a used set for now and upgrade to the konis when you do the knuckle swap like somebody else already suggested.
