SSD recommendation Mid 2010 13" MBP

[sunfalcon]

Hello! I just picked up a used mid-2010 13" MBP with 4GB memory and the stock 320GB hard drive. I loaded up 10.10.3 and while everything seems to work fine, I would like to put a SSD into it and make it more snappy. Any recommendations? 128GB is fine for what I need. I see there are a number of options from Crucial, Samsung, OCZ, Pony, etc....from about $50 - $90.

Will I really notice a difference from a lower priced one to a higher priced one? I'm sure any of them will be much faster than the drive that is currently in my machine.

Thanks!
