I would prefer to go for a model with non-working tape deck from the late 1970`s/early `80`s to pick them up at low prices then save up for the service.
The most likely reason for them not working is going to be melted belts/idler tyre etc if they are from a reputable brand such as Aiwa,Panasonic/National,JVC,Hitachi etc.
I`d check first for decent reputation repairers in your area to save on large postage costs as many of these boxes were built like tanks and were pretty heavy when compared to the later eggs with CD etc.
Late `70`s boxes may feature the lovely hypnotic VU meters too
LEDs can look good -but often they`re no match
At the end of the day sound quality is more important to me personally than looks and by the late 70`s /early 80`s good boxes had decent tape decks that would handle chrome and sometimes even metal or Fe/Cr cassettes.
I personally would skip on anything with detachable speakers and graphic equalisers (separate bass + treble controls are fine)
Some boxes also have "loudness, and/or wide stereo" settings which sometimes can be pretty good though.
You could opt for a re-branded cheaper version from one of the big companies also but you`d probably need to do a lot of research to find the original company behind them.
If your not moving it from the house then the weight is less of an issue -as is the number of batteries needed if its mostly mains powered.
Of the select masterblaster posted I`d pick the Palladium hands down in the classy looks stakes. Sencor in second but the double tape spoils it a bit for me .
The Sharp you posted looks okay -but I`ve no idea how good the sound is.
Good luck with the search and post what you manage to end up getting .
