More experience is necessary to see just how much of a handicap 10 kHz
steps are, but both VE4AMU and KE4AL made QSOs using Kenwood mobiles
limited to 10 kHz steps during the open testing pass over North
America. Of course, if you're too far off frequency to get in due to
the limited steps, you won't have to wait long to be back in! In a 500
km orbit, that Doppler shift is fast!

I understand some older 23 cm radios are limited to 25 kHz steps. You
would likely be very handicapped trying to use one of those. It's an
important issue to research when making a purchasing decision. I was
impressed with the performance of my Alinco DJ-G7T 1 watt HT on TX.
It's just too bad the RX is almost useless for satellite operations!
