It looks as though there are three options:
1) tuned hamsticks
2) 102" whip with tuner
3) screwdriver with tuner
It seems like option 1 will be the easiest to get on the air and the least expensive.
You will need a tuner with both options 1 and 2. You can tune a hamstick to a frequency but it is vary narrow and you should use an antenna analyzer to get a good match. Tunning it with the SWR meter on the radio will be difficult.
With most screwdriver antennas you don't need an antenna tuner since you can adjust the antenna up and down using the control that comes with the antenna while watching the SWR meter.
I still haven't figured out what I'm going to do for an HF antenna yet. I still like the idea of having a larger portable antenna that packs away fairly small that can be set up when needed. Like I need one more thing to set up at the campsite.

I still want something mounted to the vehicle though too so that it most likely what I will end up doing first.
I've collected a good number of antennas since I got into this hobby.
Here are the antennas I'm currently using:
-High Sierra Sidekick Screwdriver - currently on the truck with a 102" whip and N2VZ Turbo Tuner (no tuner required, turbo tuner is an automatic screwdriver antenna controller)
-Buckmaster 7-Band OCF Dipole - Portable use when I'm camping (no tuner required but can help)
-CHAMELEON V1 HF Multiband Antenna - home station, I live in a antenna restricted area (antenna tuner required)
I have also tried the following antennas, antenna tuner required with all of these:
-Hustler 80, 40, 20 mobile vertical and home station in a dipole configuration
-Hamstick 80, 40, 20 mobile vertical and home station in a dipole configuration
and a number of home brew dipoles.
Getting a good antenna tuner is a good investment if you are going to get into HF it will be part of almost every antenna setup.
The biggest problem with running the hustler's and hamsticks mobile was having to get out an switch the antennas every time you wont to switch bands.
There is a far bit of trial and error to find the best setup for your needs, if you get involved with other Hams in the area you might be able to try out some of your options before purchasing a bunch of antennas just to find out they don't work the way you where expecting. The hunt for the perfect HF antenna for your setup can take a while so once you find something that works get on the air and continue your search.
