Managed to finally get myself the two-piece Crystal front and back set from an eBay seller in the US, which was still $20 cheaper then ordering it from Power Support USA website, which are also in the US...go figure...
Anyway, I can honestly say, there is a good reason why there iPhone 4 films are more expensive then their competitors. I have owned quite a few screen protectors from several manufacturers, the last one I settled on was an SGP Crystal. However, the Power Support films blow everything else out of the water. From application right down to film quality, they are worth the premium in my honest opinion.
Well done Power Support. You provided the best protectors for the 3G/3GS and you've continued that trend with the 4G.
