Many cassette decks, although they don't come with a remote of their own, have the capability for remote control when they are connected to a receiver of the same brand with interconnect availability. Many Marantz and Denon decks are like that, and any Onkyo with "RI" (remote interlink) connection will also.
There were allot of great cassette decks built in the early nineties that rival the best decks that were made in the eighties and they all come with remote control. I wouldn't own a cassette deck that didn't have a remote, didn't have HX Pro or didn't have Dolby B&C. Then many of the early nineties cassette decks that were close to TOTL are able to make excellent recordings with the right Chrome tape.
You can also add an after market remote to some of the classic transport Naks that supported wired remotes. I have this setup on my ZX-9, great for recording from vinyl. Many Sony decks also supported wireless remotes as previously mentioned.
there is a guy on "the auction site" who does Wireless Remote Adaptors. I have had 2 specialist remotes from him. If you have a machine which has a wireless remote socket then there will probably be one available from him.
I have a remote for the Revox A700 and also for the Revox C270. By changing links internally on the C270 module, the codes are now different. I can control both machines from the same remote by changing the AV1 (A700), AV2 (C270) switch on the same remote. The remote which came with the C270 module is still in the packaging with the batteries removed. Quite cool when both machines are powered!!!
I have a Sony KA6ES Cassette Deck. This has the IR receiver window on the front panel but does not come with its own remote. The remote which comes with a Sony Amplifier "talks" to the cassette deck direct.
By the sounds of it you have some research to do!!!
All B&O decks made after Beocord 8000 are datalink compatible, the later models can be controlled fully when connected to a Beomaster 5000-5500-6500-7000, including adjustment of recording level.
