Been looking at 289 FIAs also. ERA appears to have the most accurate and is certainly a fine replica. Your other choices would be Superformance and Unique. There is a thread here from 2006 that does a great comparison to the Unique and ERA 289 FIA cars. SPF did not have their 289 car out at that time, if I'm not mistaken, so it's not in that comparison.
