I'm struggling between the two units mentioned above too...
I just sold my 3pjs. I loved it...but i want something where the wheel could be dropped to a lower position. I believe the helios is more expensive considering that you have to purchase seperately the drop down wheel.
However, on the helios - you can tilt or angle the wheel sideways as well up and down! That's pretty cool! I believe the only radio that offers that option.
On the other hand, the 3pk feels better in the hand. I like the rubber grip. The screen is bigger...but the unit looks bulkier and like D said, it's got PCM.
What about the M8 backlite vesion with the novack xxtra and synthesized receiver? I think that may end up costing more...
Choices...choices...sigh...
