I have been seeing lots of 5-bolt Focus wheels coming up for sale on craigslist lately.
Brand new alloys with tpms sensors for cheap.
Several sets of steelies and caps.
Check the regular classifieds for your area, you might be surprised.
Wheel repair is easier on steel wheels than alloy, but the lower value of steel wheels makes them often just get junked rather than fixed. I have had tire shops fix bent lips on steelies for free several times when getting a new tire.
