Well, most any modern SSD saturates SATA III bandwidth completely in terms of sustained transfer speeds, and random i/o has gotten so fast it's difficult to tell SSD's apart in day to day operations, so I'd pick the largest capacity drive you can grab for under $200 that has a minimum of a 3 year warranty.
In my personal experience, I have a difficult time distinguishing boot times on Windows 7 from a variety of SSD's in a variety of hardware configurations. The only ones that noticeably lagged was my Crucial M4, but that was heavily bottlenecked by a 1GHz AMD C-60 APU in a low-power netbook, and my previous 60GB OCz Agility 3, which was just a slow, budget SSD ($150 for 60GB was an AMAZING deal at the time) from the early days of SSDs, where SSD's suffered from shakey firmware - my OCz Agility 3 wouldn't be detected, even through my BIOS, from time to time until after I updated the firmware. What surprised me is that my old laptop with a 60GB Corsair Force F60A booted up Windows on par with the rest of my computers. I do notice a difference with Linux as Linux does boot up much faster than Windows, and the fastest one I've used is a 240GB Crucial M500 mSATA SSD on my laptop, equipped with a Core i7 4810MQ (2.8GHz - 3.8GHz) and 8GB of RAM, followed closely by my desktop equipped with a 256GB Curcial MX100 and a 4.5GHz Core i5 2500k, but I think POST might play a factor in my perception, as my laptop is much quicker to go through POST.
I know you said max of $200, but for just a bit over at $211 Crucial has the 512GB MX100, which is a very solid drive. http://www.amazon.com/Crucial-MX100-adapter-Internal-CT512MX100SSD1/dp/B00KFAGCUM
Otherwise, Mushkin has the Enhanced Chronos in the 480GB flavor for about $185 over at Newegg http://www.newegg.com/Product/Product.aspx?Item=N82E16820226372
However, if you want a high-performance SSD, for me, it would be a toss up between the Samsung 840 PRO, or the Plextor M5P Extreme, each at the 256GB capacity. Personally, for around the same price, I'd much rather take doubled the capacity at slightly slower, but still very quick over the fastest 256GB drives around that are going to be bottlenecked by the SATA interface.
