I have a 2k8 spark30 (bought 12ish months ago for £1500). It's great for enduro racing (did the Peak District Polaris, cristalp and 2 weeks in Cali earlier this year). For racing it is a fast bike, (mine is now sub 25lb having replaced wheels, bars and saddle).
My rear shock blew in Cali and Scott replaced it FOC within 2 days. I will definitely buy Scott again because of the really positive experience I had with them over this and I think their presence on the UK racing scene is a positive thing.
Mine has a 100mm fork (stock pre 2k9) and I would say it's a bit twitchy on the steep stuff and the front end is a touch low and steep, according to Scott website the head angle is the same at 70 degrees on 2k10 as on my bike. The Scott is fast but unforgiving if you tend towards black all mountain style routes (which it's not really designed for IMO, its a lightweight xc Race bike) I'd consider the genius or a Stumpjumper. I used to have an 80mm 2002 Stumpjumper FSR and it was much more relaxed geometry.
As for paying to have 1 lever to lock your forks and rear shock? (1) from what I gather the switches in the past have tended to be a bit fragile (mine has been fine though) and (2) I've been caught once going into rough stuff trying to reach down to unlock the shock and lost a few seconds but £500 for the privelege of avoiding that seems a lot. £500 is the best part of a holiday to go and ride it somewhere ace. Additionally, I tend to run my rear shock quite hard and sometimes ride lumpy long seated climbs with front shock locked and rear on traction, I don't find the bob a problem.
If you think you'll be racing then the Scott is a good bet, otherwise there are probably more "solid" options that will serve you better for peak district abuse. My spark is now boxed for the winter and I'm sure it wouldn't take too much Peak district gritty muck over the winter before things started wearing out.
Depends what you are looking for really but for a beginner I think you'll probably get more fun out of something more forgiving. Happy shopping.
