The two lenses that you have are fine lenses, but they are fairly common and, in my humble opinion, shouldn't dictate what you should invest in now that your FA has failed. The combined retail value of the lenses you have is in the $150-200 range. As they're Nikkor lenses, they are pretty easy to sell or trade in. Decide how you want to shoot and build a system around that choice rather than around a couple lenses that you happen to have. There are literally thousands of camera models to choose from.
If you really like the lenses that you have and want to keep and use them on an AF body, there are somewhere around two dozen Nikon AF film body models to choose from. Everything from the original AF model N2020 to the F6. The pro model variations, F4, F5 and F6 are more dependable and more expensive. With the exception of these and the F100, most any of the rest can be purchased for less than than $50, many in the $20-30 range. Dependability is more a function of how they have been cared for and/or stored than based on any particular model. Be careful of a the models that have rubber like coatings, particularly the N70, N80 and N90 varients. The coatings have often begun to deteriorate and are very sticky to the touch. Cleaning this off or trying to stabilize the material is a pain. The older models with the smooth finish do not have this problem.
The price range is so narrow that a higher end model with far more features can cost all of $10 more than the lower end model. For example, I would certainly purchase a N8008s over a N4004 for the few dollars difference in cost.
That's my two cents worth.
