Keep looking on Fleabay. There are a good few 3 spoke fronts on there but 5 spokes are a bit rarer.
Have a search on here in the classifieds and the classifieds elsewhere. You should get a pair of five spokes for less than £700 then you'll have a spare rear that you could keep or flog off.
A wanted add might help as well, someone might well have something up in the loft they have just tripped over gettin the Christmas deccys out
If you are worried about the condition just collect in person, that way you can avoid getting legged up with another less than perfect circle!
