Yeah I like the Glock because of how it fits my hand. Try the SR9c its a lot less blocky and thinner iirc. With a $600 budget you have all kinds of options so hit up blackwing and rent a couple to see what you like. Give me a little notice and I can bring a LC9, XD and Glock compacts.
How much are you looking to spend? A Taurus wouldn't be my first choice for a EDC gun. For an extra hundred bucks you could get into the compact Glocks, Springfields, S&Ws or Rugers. Personally I would go Glock 19 or 23 and call it a day.
For those that are worried about this gun there is nothing illegal about it other than maybe the mags. Its the same gun as this only in better condition, GLWS http://www.gunbroker.com/Auction/ViewItem.aspx?Item=266872166
