Hasegawa and the lastest Academy Eagles are well rounded in terms of detailing and over all fits. If your looking for an Echo version, I'd go with Revells as it is an excellent kit and rather inexpensive.
I too have heard really good reviews about GWH's F15's.. GWH kits are a bit steeper in price compared to Hasegawa/Academy but they are definitely worth there price!
Eduards release of the F-15 A/C is a repop of an Academy kit.. However Eduard gives you their usual goodies of photo etched, resin and multiple decal choices for markings
Flaps up,

If you would listen to everybody about the inaccuracies, most of the kits on your shelf would not have been built Too Close For Guns, Switching To Finger
