Currently using an old class 2 4gb SD card, but I borrowed a class 6 the other day (because I keep forgetting my cards) and noticed how much faster it was. I've got my eyes on a 16gb ByteStor class 10 card for £16.50, an 8gb Sandisk class 6 for £15.50 or an 8gb Integral class 10 for £11.50. I want something reliable and would rather a couple of 4-8gb cards than a single 16-32gb card however it's hard to find a trustworthy seller that still does these 'low capacity' cards 
In my position what would you buy? I'm leaning towards the Integral for speed and cost and the Sandisk for reliability.
