I was about to buy one but for about $20 more I got the AT500. I'm not sure if they're alike or not but I can tell you the AT500 is excellent for smashers and hard hitters.
The 250 is an overall good racket for its price. But if you can get the 500 for a marginal addition to the 250's price, then I would go for it. It's rated as stiff, but it isn't that rigid. The power and control is ok-good, but not outstanding, I suppose.
AT300 is gud. made in Japan, where as AT250 is made in china. I prefered AT500, there was a price diff of SGD 70, so had to opt out to AT300. Head heavy and gud offensive. Wud go in for either At500 or AT700 in the near future.
