As an old-timer, I have never gone with the flow and the idea of paying $200-$400 for seeds from an unknown source simply because they have been hyper-marketed and described as the "holy grail," lemony, citrusy, diesely, hashy, grapefruity etc. etc, makes little sense to me.
With that said, I have 6 personally-grown stashes that - at least for me - have withstood the test of time. Crystal Locomotive, Crystal Locomotive X Jack Herer, G-13 X Hashplant, Neville's Haze X C99, Neville's Haze X AK99 and Neville's Haze X Jack Herer. All seeds - with the exception of JoJo's Crystal Locomotive - were purchased pre-2000 in Amsterdam.
My Neville's Haze X Crystal Locomotive seeds are now ready and we'll see how that goes.
There may be a better Haze out there but I have yet to find one. I made the crosses to cut down on the Haze flowering time and to provide some variety.
