Hi, Trey,
I'm hoping for reports. So far, the only thing I've seen that looks like a review is in Technologies for Worship Magazine (TWFM) and it's for the UK-made high-speed USB unit. Let's start by saying this digitizes at 22.05 ks/s so it's got half the bandwidth of a CD. As I stated in my earlier post, it appears meant for spoken word and I wouldn't even consider it for music.
At least in my mix of work, quality music cassettes amount to less than 1% of what I do. It's almost all spoken word. If it is music, it's poorly recorded family music. The saddest thing is when a composer or his child comes to you with a cassette that's the only known copy of the parent's work and then you find out it's got distortion, etc.
When I speak to groups of archivists, I like to play an excerpt from an organ recording I made of Jean Langlais at the Church of the Heavenly Rest in NY City. I made it with a pair of AKG C-451 mics on a Nakamichi 550 portable on Maxell tape. I transferred it about five years ago on a Nakamichi Dragon. Sounds quite excellent.
Yes, there is a different interpretation between Nakamichi and Philips as to the published standard, see

So, while cassettes can sound surprisingly good when you use expensive machines (my Sony TCD-5M just got the best transfer of an endless loop cassette for a client because the Nakamichis wouldn't play it and the cassette itself recommended that it be run flat), most of the cassettes out there were recorded on bargain-basement recorders.
I think we need to define what the goals of the transfer are. I suspect the Graff unit provides good intelligibility of the spoken word which is very different than high fidelity music.
As far as the CONSUMER USB machines, if TracerTek is selling them, they might be a small step above what you're thinking. TracerTek tries to find good quality products for their clientele who they think of as audiophiles (and address us thusly in their emails).
I don't know if the USB cassette machines are any worse than any other cassette machine you can purchase new today. You know where I've put my money and time...6.5 Dragons with one coming someday as payment for a project I'm working on. The 0.5 is a brand-new (NOS) mechanism to replace one that might fail in one of my machines.
Cheers,
Richard
