Exactly what are you looking for? There are a lot of choices out there....
Allen Bradley
Toshiba
Yaskawa
Omron
ABB
What is the application?
How big?
I'm assuming you need 3ph 480V?
Personally, I hate Automation Direct....their crappy hardware and software has been the cause of too many nights out of town....yea, hard to beat the price....but I still hate it. BTW....they don't make the drive...it's actually someone elses with their name on it. A lot like Omega temp and pressure products.

We buy a lot of our drives from our local motor shop.
3 ph 1 HP 220v grinder. I'd prefer to go single ph 120v input for more flexibility.

Add AC Tech to the mix.
Why not the place by the bay?

I'd rather purchase from a dealer than an individual in this case.
Thanks to all for your suggestions!

We use many kinds of VFDs at the school where I manage the facilities. It has been our experience that none of them lasts more than a typical 10 years or so. Anyone have a better experience? We use them for fan motors and heating/cooling pumps.

Forget the 120V idea. Use a 240V VFD that is rated for single phase input. Many of the large dealers have an ebay store.

There's always somebody trying to push their own agenda. There is absolutely nothing wrong with the original posters preference for single phase 120 volt input. I have a few of that description myself and like them just fine.

No agenda except your own. The 120-240 step up units are more expense and complication. A real 1HP motor will not run on standard 120V outlets anyway, especially with the conversion efficiencies. For his application a 240V unit is best. Check with the Practical Machinist VFD forum for more info.

Agenda is when you tell a guy how to feel or what to do or use.
The fellow expressed a prefference and you told him to forget it. That's agenda w/o the benefit of experience.
Real cool, lots of help you are. Stick to stating your experience, if you have any on the subject. It's plain to see you don't know what you are talking about (can't run a 1 hp on 120 volt, conversion efficiencies - BS).
You look over at PM and if the files are still intact you will see I was in early ~10 years ago. I've been installing vfd's for that long also.

I would never have you install equipment for me if you run 1HP units on 120. Your "experience" is your "agenda" and is meaningless. I have been designing industrial motor control centers and equipment for 20 years so I have some real experience, not just installing boxes and wires. Of course you may be confused and think that consumer rated 1HP motors are really equivalent to a 1HP industrial motor like the OP has.

Here is but one example of a vfd with 120 volt single phase input.

As long as the amperage and voltage requirements of the motor are met you should have no problems ... except perhaps for the people that say these companies are wrong for selling such units because they don't work.

I did not say they don't work in all cases, but in this case it would be a poor choice. It is not a unit that could be expected to work for the OP's application plugged into any old 120V outlet "for more flexibility". That unit technically exceeds the capacity of a dedicated 20A 120V circuit at 80%. It will "work", -but barely. If someone wants to spec and size expensive equipment on the ragged edge, shame on them. It is not good enough in my book. I have seen too many applications where that "good enough" mentality came back to bite everyone involved. Then I had to go in and fix someone else's $$$ screw-up. If someone goes to all the trouble to run a dedicated 120V circuit they might as well run a 240V circuit and go with a unit that is less complex (no voltage boost circuits) and is not just maybe adequate for the job at hand. A grinder can see some very heavy loads for long periods.
