Well.....I am big fan of being able to replace your own tip. But the investment in time and tools to learn to do a really good job might not be worth it to you.
You can get by with sandpaper, a file, and a razor blade. Or you can get more dedicated tools.
My suggestion is to look on youtube, last time I looked there were many videos on how to replace a tip.
I used to have a setup which was a drill and all the right pins and a DIY adapter for shafts that I didn't have the right pin for. With this and various grades of sandpaper I used to do tips for folks and when I was done they looked like brand new from the maker. I was meticulous about it. But back then I only charged $5 to do a tip so it was just gas and snack money for me at tournaments. In the past ten years I have quit doing tips for other people and barely do them for myself. I don't have the patience anymore.
My suggestion is this. Find a good tip guy, ask around because they are not all good, let him do it for $10-20 and you focus on playing. The tip will last you a year probably and you will forget about the sawbuck soon enough.
