All of my machines have SSD's now and well can't go past the Samsung 830 or Crucial M4 IMHO.
Mind you thy need a bit of prepping first and I don't know about the appliances you are using but if it has a defrag component you should turn it off as the read write ability will decrease it's life. In a Windows based app then the 7 Windows will use TRIM to get rid of the rubbish and get it in optimal mode.
