Well, you have to factor in how long you'll have it for. You'll be much more happy with the 40" model rather than the 32". You pay $50 more than their 32" model, might be worth to consider, because usually people don't buy new TV's that often.

Alternative for IPS would be:

It's best to buy a new TV around September-October, which is when they'll be the cheapest. Christmas for some, but best deals can be found usually within those two months.
Sony TV's, typically have low input lag, these two Vizio's are on par, if not slightly faster, but good luck trying to feel the difference. Around the 30 ms range is fantastic for gaming, typically TV's had/have 3-4 frames more of input lag, meaning upwards of 80 to 90 ms, which you can definitely feel, even when gaming with a controller.
Bottomline, I advise you increase your budget a bit, to try to afford that 40", rather than the 32", the upgrade isn't expensive, no more than $50. Unless you feel like it'll be too big for your specific viewing distance.
Note: the Vizio's I linked are using VA-LCD's. This means that the contrast is excellent, but viewing angles suffer a little bit, though compared to typical IPS, from LG, VA creates a much better picture for movies & games. The Vizio 43" and 55" use IPS-LCD's.
All the best!
