In 2000 I bought an FE2, plus 24, 50 and 135 mm AIS lenses. I should have stopped there, but proceded to buy $$$$ worth of Nikon AF and more recently digital gear. However, to this day, the combination of the FE2, primes, and good slide films gives me the best results. When there is action, and I have to be quick, I'll use the F100. The only one of the susequent purchases that gets a lot of use is a 35 mm f2 AI lens - it has more or less replaced the 50 mm. The 135 mm AIS lens is used a lot for street photography.
I can't recommend the FE2 highly enough.
