Trans Syncro's fix or swap

My 2nd gear is impossible to shift into above 6K RPM's now, the other gears work fine but can be a bit tricky to get into. I just bought the car about 2 months ago and it's got 60,000 miles on it. I've done all other maint I can think of so far except putting new trann and diff fluids in, which I will do in a couple days.



If the new fluids don't fix it am I better off just buying a used tranny for $4-800 off ebay, or having someone open it up and fix it? How expensive would it run?



Thanks
