WTB, which Clutch combo?

[Fatboy 18]

OK, probably going to open up a minefield here but am looking at getting a replacement clutch for my gen II 2000 GTS
I have owned the car since 2008 and not had a problem with the clutch but being in the UK I figured it would be wise to have a spare on the shelve for that moment when it finally lets go!

My driving involves mainly going to car meets and charity track joy rides, not really flat out racing on track. I do like to light up the rear rubber every now and again

I have seen Clutch kits start from a couple of hundred dollars on the bay to over a thousand dollars? LUK, Spec clutches? Stage 1, Stage 2, etc.... any of these any good?

Sadly I run the car on a very very tight budget, so going for something that costs thousands is not really an option.

Only been to the drag strip once and ended up breaking a half shaft ! So the clutch worked ok.

I have never had the clutch out of the car, so I don't know what is in there?

So what would you recommend?
Thanks.
