None of the above. I built the PAC-12 antenna http://www.njqrp.org/pac-12/
which works great with my Elecraft K1. The one change I made to the design was instead of using aluminum rod I used 1/4" all thread which is available cheap at Lowe's or Home Depot. I also found a cheap tripod on ebay ($10) to screw the antenna to. Hookup wire for the coils is still available at Radio Shack and with coils and ground plane wires you'll need about three spools.
Good luck with whatever you choose.
