$400 is too much.
"Which will likely still have a 1" head tube and threaded fork, which is not adjustable - this really limits your stem and handlebar options...... "
Don't worry about this, you can put an adapter on it and use any modern stem/bar, but that's even more money into a 20 year old bike.

If you can get it for under $200 and it is working well then maybe.
