I have about that (miles equivalent

) on my 2000, without any issues relative to reliability.
On my 2000, stock, it was very abrupt on-off throttle but was fixed with the PC3. I've heard that they had improved the calibration later on, but don't know how well.
Suspension was my other issue when stock. Very harsh ride, to the point of throwing me out of the seat over freeway expansion joints. This was fixed with on Ohlins shock and Dan Kyle reworked shocks. Completely transformed the bike.
These would be 2 things to watch for when test riding the bikes. If they aren't a problem, then you don't need to invest in the parts ... same with the PC3, maybe the one without didn't need it.
Other than that and some ergonomic adjustments (Seargent seat and Sato adjustable clip-ons to ease the wrists), and a couple more teeth on the rear sprocket, it is a very fun and comfortable ride ... for the sporty side of it.
Good luck.
