Ida registration and the required sticker stating so has been negated quite quite some time ago....
Now consumer devises aren't their concern anymore.
Years ago every time we had an analog modem/ISDN modem version release, we had to bring it to iDA for compliance (then Ida was known as TAS)
We recently got a dozen UHF comms for local use, cleared customs as long as the declaration was signed and the frequencies weren't in the restricted range.
My 2 cents, since my former employer used to resell telecom and RF products, fret not.
Unless you are planning to resell, in volume, it's not even an issue
If you like a particular model, as long as it can work on the local phone network, worry not
