I don't follow the latest gear as much any more, but the Icom 706 line of mobile HF/VHF radios is probably the best value for what I think you want to do (HF mobile and probably some 2 meters). They've been around for quite a while and it shouldn't be too hard to find a decent used older model.

If you really want to start doing HF, avoid low-powered QRP radios like the Yaesu FT-817 to begin with. 5 watts just isn't enough for SSB except as a novelty. Start with a 100 watt radio and you'll have a lot more success.

Hamstick antennas (and their clones) seem like a great deal but for the lower bands, especially 40 and 80 meters, they're not very efficient. For home use, the good old G5RV is still the winner. For mobile, a 20m hamstick is a decent start. For 40 or 80 meters, something with a bigger diameter coil like a Hustler or "bug catcher" will help a lot. But mobile HF is tricky. Depending on the vehicle, you might end up needing to do some work to eliminate RF noise and electrically connect more of the body and frame together.

Good luck and 73s!
