Links
Here are a few websites I like.
PentaxForums.com Is a great forum of photographers, they have an amazing page of Pentax lens reviews.
DPreview I have been using this site for lens reviews. I like the fact that they have more technical information than most review sites, but they are also very harsh so don't let them sway you too much haha.
KEH A great website for finding used equipment at decent prices; such as lenses.
SteadDSLR a great "Steady Cam" rig for DSLR cameras.
