Every time I purchase a new racquet - even after much research - I vow never to come to this site since my head will almost undoubtedly be turned by some other racquet. I, of course, fail to carry through with this, since this board is so much fun.
The Dunlops are nice sticks, but there's something about it that just don't work for me. Perhaps I'm too fickle and easily swayed by marketing, but they don't seem hi-tech enough for me. Again, I have a lot of the old classics (or did at one time) and while they have their charm, they just seem so dated. To this end, I believe in modern tennis - and believe that the spin-game is here to stay for the foreseeable future. Serve and volleying just appears antiquated, like using a libero/sweeper in soccer - as such, the racquet's ability to volley is of much less importance to me than ground strokes or returns for instance. As such, Dunlop just comes across as a company who makes very solid sticks for guys in their 40s or early 50s that have a certain perspective on what a racquet should be like and want a quality reproduction of that (much like Pro Kennex and to an extent Yonex). Nothing wrong with that if that's your game, but it's not mine. That being said, the 200 Tour is a club and is fun because of it - also believe they can be found new for under $100.00.
In terms of the buzz/vibration, I believe some racquets are indeed better than others but that a happy medium can be found with the right string choice for almost all racquets. Put a full bed of stiff poly on an APDGT and it will be noticeably buzzy, sure - but natural gut (or even quality multi), to a lesser degree and none at all w/ blu tack/silicone. To me, however, I value performance over feel. For example, I recently sold off a pair of Fischer Vacuum Pro 90s. A much lauded racquet here - legendary feel and precision. This is true, however, the racquet is almost totally dead in the upper hoop and has very little inherent power (even with a full, traditional stroke). I wasn't willing to give up 10-20% of velocity for feel. Maybe your the same?
Also, and since I believe this will be a process rather than a quick fix, take a look at ****. Perform a search on the racquets you're interested in and see what price you can actually sell them off for if you get tired of them. In this regard, the APDGT or the PDR may have higher resale than something like a Exo Tour 100.
Finally, have you looked at the Head Microgel Radical MP? It checks off a few of the boxes you indicated and is dirt cheap right now. Although I much prefer the APD, the MG Radical is still a great racquet with less power, great feel, and low weight. Also, it's 18x20, so more suitable to your standard stroke.
lol.
