The perfect radio is all based on one's preferences and use cases.
Price/Performance/Usability ratio, simplicity, features or lack of all play a role.
I have two like new ic-718s, and I paid half the price of a 7300 for those two.
Don't really care for the aesthetics, or lack of in the 7300, as I am of the knob twister generation, and despise touch screens.
I look at a price/usability ratio and the 718 fits into that model for me.
I don't really want an expensive radio that requires a big fat manual to figure out complex menu systems.
A cheap radio with a power button, tuner knob and volume knob are the only basics I require, and the 718 provides a cheap basic platform.
Yes I admit I wanted the 7200 more but I also find them to be unobtanium. Gotta love those handles too!
I prefer to have many low priced rigs in different shacks/locations than one high priced one.
If a tornado hits your house and destroys your only shack, you are now out of the EMCOMM game.
As for no built in auto tuner, I prefer a manual tuner anyway.
Good luck tuning up your rain gutter or experimental contraption of an antenna in an emergency with some auto tuners.
As an experimenter not a contester, the 718 with no built in auto tuner is good enough for me.
I am also not in such a hurry that I need an auto tuner. I can tune in less than 10 seconds as is.
A great low cost add on to the 718 and other ICOM radios:

All for as little as $10.00 too!
As for digital modes, the SignalLink works very well with this radio.
