You can't really get good racket recommendations as they all differ greatly depending on your playing style. On one end of the spectrum you have ones that deliver great power at the expense of control, and at the other end of the spectrum you have ones with great control but little power. Your choice of racket depends on exactly how big of a swing you take and how much power you can generate on your own. For example the Hammers generate a lot of power, so you can hit hard with little effort but you lose a lot of control in the process. On the other side, there are weaker rackets where you can pinpoint your shots well, play the net easily, but you really have to have a nice hard swing to really get any power on the ball.
One of the best resources on the net for tennis rackets is

They have pretty much every racket out there along with their specs and some professional and user reviews. The user reviews are somewhat worthless though as 95% of them are always positive, and the 5% that are negative are usually because the person is using the wrong racket for their style. So the goal is really to find the best racket for your style, although you can always adapt your style to your racket to some degree.
I used to play with a racket that was more on the power end of the scale than the control end. I'd hit hard, but I'd also hit a lot of balls deep and had trouble coming to the net. I switched to more of a control racket and the opposite started happening, I'd hit a lot of balls into the net as I wasn't used to having to hit the ball so hard, but playing the net was a bit easier as I could make balls die easier. Eventually you get used to either of them, but now I prefer more on the control side. I'm currently using a Prince More Approach racket, which is more of a control racket, but has a bit more power than the previous control racket I used (Prince Triple Threat Warrior).
But really, its just a matter of finding one suitable to your tastes. Most tennis shops let you demo rackets, so you can try a few out before buying so you can see the subtle difference and figure out which you like best. I wouldn't recommend just buying a racket blindly - try a few out to see which suits you the best.
