Could've meant anything....most people don't know "Samsung" is Korean for three stars or 'Tristar'

But yeah, wasn't nice being caught back in the day......happened to me
(Luckily it's all a bit less serious nowadays.)
To the Original Poster 'Falconuk', (no personal, sorry)
It depends what you want or expect from CB as to what equipment you're after.....
Good antenna - are you gonna be homebase or mobile?
Are you just going to be chatting to mates on UK FM? You mention the SS6900 so obviously expect a bit more

UK frequencies are legal only when using FM at 4 watts and Euro/CEPT/US/Mid-block, (b*gger me they use various descriptions!), you can use FM/AM/LSB/USB.....etc. etc. Full details at OFCOM if you want the the legal route.
If you go fully legal.... you're gonna miss the fun of 'Freeband DXing'!!!

'Freeband'(?), didn't us old farts call it Hi-Band?...Hi-block?...High?....Top of the shops?

Whatever, all the fun stuff that happens around 27.555MHz, the triple 5, the international CB DX calling frequency, (amongst others).
Basic, legal CB will only get you so far such as chatting to your mate five miles down the road. Which is fine

Legal Euro with it's AM and Sideband modes will get you a bit further.....until....
The 'skip' comes in
Suddenly you'll find you can be chatting to someone in Europe, or further, or even the USA!
That my friend, is what excites a lot of us with CB.
But why limit yourself?
The 'skip' comes in and now you can hear every potential DJ playing music on UK 19, even with Euro frequencies you get European numpties playing music on their frequencies.....so you skidaddle along to the 'Freeband' frequencies and hear the DX CBers shouting CQ for all their worth!

(Of course you still get Numpties there too....just less of them

)
For a lot of us CBers, (and other radio operators alike), it's the proverbial gold at the end of the rainbow!
But......
If you want to go fully 'legal' you might consider the Amateur Radio or Ham route. Pass your test, loads more frequencies/bands to use...etc. etc.
Don't forget, a lot of Hams started on CB and a lot of them are still here using CB today

'Rotel240's suggestion is as good as any, knock yourself out.
Honestly, as far as 'legalities' are concerned it's not like you're hurting someone. A few extra watts, an 'illegal' rig, DXing on the Freeband, none of it is going to kill someone.....unlike using a mobile phone whilst driving eh?

Laws are there to protect people, or should be and nothing else.
Anyway, hope my waffling helps you out.
"Legal", tut. To paraphrase....
"He's not the Messiah......(altogether now), he's a very naughty boy!"
All the best,
