The SB2 is electronically and functionally identical to the SB3. The big difference is that the SB3 has an internal WiFi antenna. The SB2 has more room inside for future mods.
I would suggest that you download the SB software and play around with it before buying. Or you can just buy one and take advantage of the 30 day return policy if you don't like it. The SB software is a lot different than Itunes and most people seam to prefer Itunes.
I have a Bolder Cable modded SB2 with the deluxe power supply. I could not be happier.
Good Luck,
