For my first playing cue, I bought a Players sneaky pete and put a Kamui Black Soft Tip on it. It was a pretty great cue for $75 but I'll be honest...I only played with it for a few months. The shaft was smooth and straight but the taper or thickness didn't feel good to me. It felt too thick to me. I kept it and I use it for my home table for guests and they like it.
My advice is to buy a nice used cue. My theory is that you need to try some cues out before you find the one you really like. If you buy something used, it is essentially free no matter what you pay for it as long as you get a decent deal. If I buy a $200 used cue and don't like it, I can sell it for $200 or close to it and in the mean time got to use a good cue and learn a little more about what I like in a cue. If you do this a few times you can figure out what you want without losing a bunch of money on new cues. You could also then have the experience to buy a custom cue to your specs. (weight,balance point, joint, etc.)
Another suggestion i have is to buy a bunch of different size weigh bolts. The are cheap and can really make a cue feel different based on different weights and balance points.
Then, once you find the right cue...try to play with it forever so you can get used to the amount of deflection and feel.
